Abstract: The MURAVES (MUon RAdiography of VESuvius) project is a joint activity participated by INGV, INFN and the Universities of Naples “Federico II” and Florence. The collaboration, following the experience gained within the previous INFN R&D project Mu-Ray, is currently completing the production of a robust four square meter low power consumption detector to be installed on the flank of Mount Vesuvius, an active volcano located on the western coast of Italy. The detector is supposed to collect data for at least one year, thus allowing performing a scan of the structure of the Vesuvius volcanic cone. In this work the status of the project and some parallel activities on muon radiography are presented.

Abstract: The NA62 experiment at CERN reports searches for $K^+\to\mu^+N$ and $K^+\to\mu^+\nu X$ decays, where $N$ and $X$ are massive invisible particles, using the 2016-2018 data set. The $N$ particle is assumed to be a heavy neutral lepton, and the results are expressed as upper limits of ${\cal O}(10^{-8})$ of the neutrino mixing parameter $|U_{\mu4}|^2$ for $N$ masses in the range 200-384 MeV/$c^2$ and lifetime exceeding 50 ns. The $X$ particle is considered a scalar or vector hidden sector mediator decaying to an invisible final state, and upper limits of the decay branching fraction for $X$ masses in the range 10-370 MeV/$c^2$ are reported for the first time, ranging from ${\cal O}(10^{-5})$ to ${\cal O}(10^{-7})$. An improved upper limit of $1.0\times 10^{-6}$ is established at 90% CL on the $K^+\to\mu^+\nu\nu\bar\nu$ branching fraction., Comment: Updated version published as Phys.Lett. B816 (2021) 136259

Abstract: A review of selected recent results from experiments studying rare kaon decays in Europe is given. The results from the NA62 experiment at CERN are summarized in the first part of this report. The experiment produced a new preliminary upper limit on the $K^{ + } \to \pi ^{ + }\nu \bar{\nu }$ branching ratio of 1.85 × 10^−10 at 90% CL, based on the data recorded in 2016 and 2017. NA62 also performed searches for production of heavy neutral leptons (N) in $K^{ + } \to \ell ^{ + }N$ ($\ell = e,\mu $), and for lepton number violating processes $K^{ + } \to \pi ^{ - }\ell ^{ + }\ell ^{ + }$ ($\ell = e,\mu $). No significant signal was observed in these searches, and the world-leading upper limits have been set. In the second part of this review, we summarize the first observation and the branching ratio measurement of the $K^{ \pm } \to \pi ^{ \pm }\pi ^{0}e^{ + }e^{ - }$ decay by the NA48/2 experiment, a new preliminary measurement of the $K_{S} \to \pi ^{ \pm }\mu ^{ \mp }\nu $ branching ratio by the KLOE experiment, and a new upper limit on the $K_{S} \to \mu ^{ + }\mu ^{ - }$ branching ratio by the LHCb experiment.

Abstract: NA62 is a fixed target kaon experiment at the CERN SPS which aims at measuring the branching ratio of the $K^+\to\pi^+\nu\bar{\nu}$ decay with 10% precision. This ultra-rare kaon decay is theoretically extremely clean and an ideal place to look for physics beyond the Standard Model. The NA62 experiment has been running in 2016-2018 and has accumulated a large amount of kaon decays. The final result of the $K^+\to\pi^+\nu\bar{\nu}$ analysis using the 2016 dataset is discussed as well as prospects for the analysis of the 2017 dataset. NA62 also has sensitivity to various other rare and forbidden kaon decays, as well as some hidden sector models. The results of a search for the Lepton Number Violating decays $K^+\to\pi^-\ell^+\ell^+\ [\ell=e,\mu]$ is presented, along with new limits on the existence of a dark photon., Comment: 6 pages, 2 figures, talk given at ALPS2019, Obergurgl, 22-27 April 2019

Abstract: The NA62 experiment at the CERN SPS reports a study of a sample of 4 × 109 tagged π0 mesons from K+ → π+π0(γ), searching for the decay of the π0 to invisible particles. No signal is observed in excess of the expected background fluctuations. An upper limit of 4.4 × 10−9 is set on the branching ratio at 90% confidence level, improving on previous results by a factor of 60. This result can also be interpreted as a model- independent upper limit on the branching ratio for the decay K+ → π+X, where X is a particle escaping detection with mass in the range 0.110–0.155 GeV/c2 and rest lifetime greater than 100 ps. Model-dependent upper limits are obtained assuming X to be an axion-like particle with dominant fermion couplings or a dark scalar mixing with the Standard Model Higgs boson.

Abstract: The RICH detector of the NA62 experiment is one of the key detectors to achieve the muon rejection needed in the search for the ${K^ + } \to {\pi ^ + }\nu \bar \nu $ decay, performed by NA62. Since $BR({K^ + } \to {\mu ^ + }\nu )$ is higher than $BR({K^ + } \to {\pi ^ + }\nu \bar \nu )$ by more than 9 orders of magnitude, it represents one of the most relevant background contributions. Its rejection is performed with kinematic reconstruction of the event and identification of the charged particles in the final state (pions against muons). The Ring Imaging Cherenkov detector (RICH) gives a muon rejection higher than a factor 100 in the momentum range 15-35 GeV/c, and measures the track crossing time with a resolution better than 100 ps. It is also exploited to provide trigger for charged particles. In this contribution the RICH detector will be described, together with its basic performance, the mirrors alignment procedure and its usage in ${K^ + } \to {\pi ^ + }\nu \bar \nu $ search.

Abstract: The search for an invisible vector boson from $\pi^0$ decays at the NA62 experiment at CERN Super Proton Syncrotron (SPS) is discussed. Within the proposed models for physics beyond the SM, hidden sectors consisting of new, light, weakly-coupled particles are a particularly compelling possibility. Thanks to the high beam intensity, the extremely good performance of the photon detection systems, particle identification system and the detectors timing, NA62 is suited to search for these new particles. Here the search for a dark photon from $\pi^0$ decays using the $k^{+}\rightarrow \pi^+\pi ^0$, $\pi^0\rightarrow A^1\gamma$ decay chain is illustrated. The result from the analysis of a sub-sample of 2016 data is reported, corresponding to 1% of the full statistics collected in 2016-2018. A new upper limit on the $\pi^0\rightarrow A^1\gamma$ branching ratio has been set as a function of the dark photon mass, thus producing a new upper limit on the dark photon coupling parameter.

Abstract: The decay $ {K^ + } \to {\pi ^ + }v\bar v $, with a very precisely predicted branching ratio of less than 10−10 in the Standard Model framework, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure the branching ratio of such decay with a decay-in-flight technique, novel for this channel. The main goal of NA62 is to measure such Branching Ratio of $ {K^ + } \to {\pi ^ + }v\bar v $ with an accuracy better than 20%. This will be achieved by collecting up to 100 $ {K^ + } \to {\pi ^ + }v\bar v $ events with a background contamination at the level of 10%. The NA62 detector was commissioned in 2014 and 2015 and the experiment took physics data from 2015 to 2018. NA62 has already published the result of the 2016 data analysis. The 2017 data analysis is in progress, the single event sensitivity reached and the evaluation of the main backgrounds will be shown in this contribution.

Abstract: The NA62 experiment at CERN Super Proton Synchrotron was designed to measure BR(K+ → π+νv¯) with an in-fight technique, never used before for this measurement. This decay is characterised by a very precise prediction in the Standard Model. Its branching ratio, which is expected to be less than 10−10, is one of the best candidates to indicate indirect effects of new physics beyond SM at the highest mass scales. NA62 result on K+ → π+νv¯ from the full 2016 data set is described.Also a search for an invisible dark photon A′ has been performed, exploiting the efficient photon-veto capability and high resolution tracking of the NA62. The signal stems from the chain K+ → π+π0 followed by π0 → A′γ. No significant statistical excess has been identified. Upper limits on the dark photon coupling to the ordinary photon as a function of the dark photon mass have been set, improving on the previous limits over the mass range 60 - 110 MeV/c2.

Abstract: The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the K + → π + ν ν ¯ with a decay-in-flight technique and took data in 2016–2018. The statistics collected in 2017 allows NA62 to achieve the best up–to–date single event sensitivity for K + → π + ν ν ¯ corresponding to more than 2 Standard Model K + → π + ν ν ¯ expected events. The analysis of the 2017 data has revealed 2 candidate K + → π + ν ν ¯ events, while 1.5 background were expected. Together with the candidate found on the 2016 data, this result leads to 1.85 × 10−10 as preliminary upper limit at 90% C.L. on the branching ratio of the K + → π + ν ν ¯ decay. The 2017 data also allow NA62 to achieve the best up–to–date sensitivity on the search for the π 0 → invisible decay.

Abstract: The RICH detector of the NA62 experiment is one of the key detectors to achieve the muon rejection needed in the search for the K + → π + ν ν ¯ decay, performed by NA62. Since BR(K + → µ + ν) is higher than BR( K + → π + ν ν ¯ ) by more than 9 orders of magnitude, it represents one of the most relevant background contributions. Its rejection is performed with kinematic reconstruction of the event and identification of the charged particles in the final state (π + against µ +). The pion identification efficiency using the RICH detector is measured to be 83% in the momentum range between 15 and 35 GeV/c, with a misidentification probability for muons of 0.2%, while the track crossing time is measured with a resolution of 70 ps. The RICH detector is also exploited to provide trigger for charged particles with an efficiency greater than 99%.

Abstract: Flavour physics is one of the most powerful fields for the search of new physics beyond the Standard Model. The kaon sector with the rare decay K+ → π+νν̅ provides one of the cleanest and most promising channels. NA62, a fixed target experiment at the CERN SPS, aims to measure BR (K+ → π+νν̅) with 10% precision to test the Standard Model validity up to an energy scale of hundreds of TeV. NA62 had dedicated data taking for the K+ → π+νν̅ measurement in 2016 and 2017 and will continue in 2018. Here preliminary results on a fraction of 2016 dataset are presented. The analysis of the complete 2016 data sample is expected to achieve the SM sensitivity.

Abstract: The NA62 experiment at the CERN Super Proton Synchrotron (SPS) is currently taking data to measure the ultra-rare decay K + → π + ν ν ¯ . The high-intensity setup, trigger flexibility, detector performance and high-efficiency vetoes make NA62 also suitable for direct searches of long-lived, beyond-the-Standard-Model particles, such as Heavy Neutral Leptons (HNLs), Axion-Like Particles (ALPs) and Dark Photons (DPs), moreover, many rare and forbidden decays are studied at NA62. The status of all these searches is reviewed, together with prospects for future data taking at NA62 after the CERN Long Shutdown 2 (LS2).

Abstract: The decay $K^{+} \rightarrow \pi^{+} v \overline{v}$, with a very precisely predicted branching ratio of less than $10^{-10}$, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the $K^{+} \rightarrow \pi^{+} v \overline{v}$ with a decay-in-flight technique. NA62 took data so far in 2016-2018. Statistics collected in 2016 allowed NA62 to reach the Standard Model sensitivity for $K^{+} \rightarrow \pi^{+} v \overline{v}$, entering the domain of $10^{-10}$ single event sensitivity and showing the proof of principle of the experiment. Thanks to the statistics collected in 2017, NA62 surpasses the present best sensitivity. The analysis strategy is reviewed and the preliminary result from the 2017 data set is presented.The NA62 experiment at CERN collected a large sample of charged kaon decays into final states with multiple charged particles in 2016-2018. The sensitivity to a range of lepton flavour and lepton number violating kaon decays provided by this data set improves over the previously reported measurements. Results from the searches for these processes with a partial NA62 data sample are presented.

Abstract: Fixed-target experiments present a complementary tool for studies of the beyond Standard Model physics in either direct searches for weakly coupled states in $\mathcal{O}(10^{7})$ − $\mathcal{O}(10^{9}) eV/ c^{2}$ mass scale or indirect searches for deviations in known processes induced by physics of much higher energy scales. The NA62 experiment dedicated to study of ultra-rare kaon decays is competitive on both these fronts thanks to its immense sensitivity and possibility of data-taking inbeam-dump mode,in which statistics of $\mathcal{O}(10^{16})\mathrm{POT}$ has been collected and another $\mathcal{O}(10^{18})\mathrm{POT}$ will follow in 2021-2023 run. This proceedings will present the published results, discuss the current status and show the future prospects of searches for exotic particles at NA62, specifically heavy neutral leptons, dark photons and axion-like particles.

Abstract: Fixed target experiments are a useful tool in the search for very weakly coupled particles in the MeV-GeV range, which are of interest, e.g. as potential dark-matter mediators. The NA62 experiment at the CERN SPS is currently taking data for rare kaon decay measurements. Due to the high beam energy and hermetic detector coverage, NA62 also has the opportunity to directly search for a multitude of long-lived beyond-Standard-Model particles, such as dark photons, dark scalars, axion-like particles, and heavy neutral leptons. We review the status of these searches and give prospects for future data taking at NA62.

Abstract: In this paper we present the results of the search for heavy neutral lepton (HNL) production in charged kaon decays using a data sample collected with a minimum bias trigger by the NA62 experiment at CERN in 2015. Upper limits at the $10^{-7}$–$10^{-6}$ level are established on the elements $|U_{e4}|$ and $|U_{\mu 4}|$ of the extended neutrino mixing matrix for HNL masses in the range 170–448 $\text {MeV/c}^2$ and 250–376 $\text {MeV/c}^2$, respectively.

Abstract: NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the $K^{+} \rightarrow \pi^{+} \nu \bar\nu$ decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions. For this purpose, innovative techniques have been developed, in particular, in the domain of low-mass tracking devices. Detector construction spanned several years from 2009 to 2014. The collaboration started detector commissioning in 2014 and will collect data until the end of 2018. The beam line and detector components are described together with their early performance obtained from 2014 and 2015 data., Comment: Accepted by JINST, few typos fixed, authors.xml file added, 121 pages, 77 figures

Abstract: The decay K + → π + v v ¯ , with a very precisely predicted branching ratio of less than 10−10, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K + → π + v v ¯ with a decay-in-flight technique, novel for this channel. NA62 took data in 2016, 2017 and 2018. Statistics collected in 2016 allows NA62 to reach the Standard Model sensitivity for K + → π + v v ¯ , entering the domain of 10−10 single event sensitivity and showing the proof of principle of the experiment. The analysis data is reviewed and the preliminary result from the 2016 data set presented.

Abstract: Very weakly coupled new-physics particles in the MeV-GeV range appear as mediators in various “portals” to a hidden sector. Their interaction with Standard Model particles is feeble and these states are usually long-lived, so that the experimental search fully profits of a high-intensity setup, such as that of fixed-target experiments. Within the vector portal hidden-sector model a dark photon might exist which predominantly decays to dark matter particles. A search for such an invisible particle has been performed, exploiting the efficient photon-veto capability and high resolution tracking of the NA62 detector at CERN. The signal stems from the chain K + → π + π 0 followed by the π 0 decay to a photon-dark-photon pair. No significant statistical excess has been identified. Upper limits on the dark photon coupling to the ordinary photon as a function of the dark photon mass have been set.

Abstract: The NA62 experiment at the CERN SPS provides unique opportunity to study rare and forbidden decays of K + mesons. Using the data collected in 2017 a search for the lepton number violating decays K + → π − µ + µ + and K + → π − e + e + has been performed. New upper limits on the branching ratio have been obtained: 4.2×10−11 for the muon and 2.2×10−10 for the electron mode (90% confidence level). These results improve the existing limits by factors of 2 and 3 respectively.

Abstract: Precise measurements of the branching ratios for the flavor-changing neutral current decays K → π ν ν ¯ can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. It is important to measure both decay modes, K + → π + ν ν ¯ and K L → π 0 ν ν ¯ , since different new physics models affect the rates for each channel differently. The NA62 experiment at the CERN SPS will measure the BR for the charged channel to better than 20%. The BR for the neutral channel has never been measured. We are designing the KLEVER experiment to measure BR( K L → π 0 ν ν ¯ ) to ∼20% using a high-energy neutral beam at the CERN SPS. The boost from the high-energy beam facilitates the rejection of background channels such as K L → π 0 π 0 by detection of the additional photons in the final state. On the other hand, the layout poses particular challenges for the design of the small-angle vetoes, which must reject photons from K L decays escaping through the beam exit amid an intense background from soft photons and neutrons in the beam. We present findings from our design studies, with an emphasis on the challenges faced and the potential sensitivity for the measurement of BR( K L → π 0 ν ν ¯ ).

Abstract: The Ring Imaging Cherenkov detector of the NA62 experiment at the CERN SPS is a key element of particle identification in the NA62 experimental strategy. According to the NA62 requirements, the RICH identifies π + and μ + in the momentum range between 15 and 35 GeV/c with a muon rejection factor of O(10 2 ), measures the arrival time of charged particles with a precision better than 100 ps and is one of the main components of the NA62 trigger system. After the commissioning in 2014–2015, the RICH detector has been successfully operated during the 2016, 2017 and 2018 data taking periods of NA62. The main design aspects and operational characteristics of the NA62 RICH are described and results on its performance, directly measured with data, are presented.

Abstract: The K+ → π+νν decay is characterised by a very precise prediction in the Standard Model (SM). Its branching ratio, which is expected to be less than 10−10 is one of the best candidates to indicate indirect effects of new physics beyond SM at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K+ → π+νν decay with an in-fight technique, never used before for this measurement. NA62 is taking data since in 2016 with the goal to reach the SM sensitivity, an accuracy of the order of 10%. In 2017 it has then collected 10 times more statistics and a similar amount of data is expected from the 2018 run. The preliminary result on K+ → π+νν from the full 2016 data set and prospects for future developments are presented.

Abstract: Fixed target experiments are a particularly useful tool in the search of very weakly coupled particles in the MeV-GeV range that could explain the baryon asymmetry of the Universe, the nature of the Dark Matter and the origin of the neutrino masses and oscillations. The NA62 experiment at the CERN SPS is currently taking data to measure the rare decay $K^{+}\rightarrow\pi^{+} v \bar v$. Owing to the high beam-energy and high beam intensity, a long decay volume and a hermetic detector coverage, NA62 also has the opportunity to directly search for a plethora of hidden-sector particles, both in visible or invisible final states. We will detail on status and prospects of these searches, with special focus on those that can be performed with the experiment operated in beam-dump mode.

Abstract: This paper reviews recent results form the NA62 and NA48 experiments at CERN. NA62 has searched for the K → πνν¯ with an in-flight decay technique. The analysis of 1.2 · 1011 decays has found one event compatible with the Standard Model prediction, giving an upper limit for the branching ratio of 1.4 · 10-9 (95% CL) in the background assumption. Prospects for improvements in the measurement are given. Results on the Kl3 decay form factors from NA48/2 are presented as well as the first observation of the decay K± → π ± π0e+e- and the measurement of its branching ratio from the same experiment.

Abstract: © Copyright owned by the author(s) under the terms of the Creative Commons. NA62 is successfully running in the North Area of the CERN SPS with the main goal of measuring the BR(K+ → π+νν) with 10% accuracy. Owing to the high beam energy and high beam intensity, the long decay volume and the hermetic detector coverage, NA62 also has the opportunity to directly search for a plethora of hidden-sector particles, both in visible or invisible final states. A large variety of searches for hidden sector particles can be performed using kaon decays and broad and rich physics programme is being proposed for the 2021-2023 data taking, including ∼ 1018 protons-on-target (pot) collected when the experiment is operated in dump mode. We will detail the status of the first analysis based on the 2 ×1015 pot already collected in dump mode.

Abstract: The precise measurement of the branching ratio of an ultrarare decay K+ → π+vv¯ (~10-10 according to the calculation within the Standard Model) allows to probe New Physics via indirect effects at mass scales higher than those accessible at the LHC. The NA62 experiment at the CERN SPS is aimed at measuring this branching ratio with the 10% precision. To achieve such level of precision, a novel decay-in-flight technique is used. The statistics collected during the first NA62 physics run in 2016 allowed to demonstrate the proof of the experimental method and obtain O(10-10) single event sensitivity. The preliminary results based on the 2016 data set are described.

Abstract: $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ decay with 10\% precision. NA62 took data in 2015 and 2016 reaching the Standard Model sensitivity. The experiment will be reviewed, and recent results and prospects will be presented, also on heavy neutrinos limits.

Abstract: The NA62 experiment at the CERN SPS is designed to measure the branching ratio of the ultra-rare decay K+->pi+ nu nubar with 10% precision. For this purpose the experiment aims to collect of the order of 100 K+->pi+ nu nubar events which would require at least 10^13 K+ decays in the fiducial volume of the detector. The large sample of K+ decays that will be available at NA62 allows the experiment to carry out a rich program for rare and forbidden K+ and pi0 decays, including lepton flavour and/or number violating modes, sterile neutrinos, exotic particles (e.g. Dark Photons). NA62's potential for such searches in K+ and pi0 decays is discussed, with initial sensitivity estimates. In addition, plans for continuing the experiment after 2021 (Long Shutdown 2) are presented, including in particular the possibility to operate in a beam-dump mode for exploring various Dark Matter scenarios.

Abstract: The flavor physics sector allows us to explore the possible extensions of the Standard Model (SM) in a complementary approach to the direct searches conducted i.e. at the Large Hadron Collider (LHC). New physics contributions at high energy scales can manifest themselves in low energy phenomena provided that the observables are carefully chosen, precisely measured and compared to accurate predictions. A stringent test of the SM predictions is the observation of the rare decay K+ to pi+ nu nubar. The NA62 experiment at CERN is designed to measure the branching ratio (BR) of this decay with 10% precision. NA62 has been successfully launched in October 2014, took data in pilot runs in 2014 and 2015 achieving the commissioning of the detectors and the designed beam intensity. The NA62 experimental setup is described and the quality of data collected in view of the final measurement is reported.

Abstract: The $\pi\nu\nu$ is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the $K^+\rightarrow\pi^+\nu\bar{\nu}$ decay with 10\% precision. NA62 took data in 2015 and 2016 reaching the Standard Model sensitivity. The KOTO experiment in Japan is investigating the decay $K_L\rightarrow\pi^0\nu\bar{\nu}$ reaching a higher background suppression. Both experiments are reviewed, and recent results and prospects are summarised.

Abstract: Fixed target experiments are a particularly useful tool in the search of very weakly coupled particles in the MeV-GeV range, which are of interest as potential dark matter mediators. Owing to the high beam energy and a hermetic detector coverage, NA62 also has the opportunity to directly search for a variety of long-lived beyond the Standard Model particles, such as axion-like particles and dark photons. Furthermore, the large sample of K + decays available at NA62 allows a rich program for rare and forbidden decay studies. In this paper the status of these searches is reviewed, giving prospects for future data taking at NA62.

Abstract: NA62 is a fixed target experiment located at the CERN SPS which aims to perform flavour physics studies in the charged kaon sector with an unprecedented precision. Due to the abundance of kaon decays with a po in the final state, NA62 is also a perfect environment to measure the neutral pion characteristics. NA62 collected a large sample of charged kaon decays with a highly efficient trigger for decays into electrons in 2007. We report about the measurement of the po electromagnetic transition form factor slope parameter in the time-like region. Between 2008 and 2014 the NA62 apparatus underwent an intense upgrade phase to improve the physics sensitivity of the experiment to precisely measure the Br (K+ !p+n ¯ n). NA62 took data in pilot runs in 2014 and 2015 reaching the final designed beam intensity. The quality of data acquired in view of the final measurement is presented.
