Abstract: The first search for ultra-rare $K^+$ decays into the $\pi^+e^+e^-e^+e^-$ final state is reported, using a dataset collected by the NA62 experiment at CERN in 2017-2018. An upper limit of $1.4\times 10^{-8}$ at 90% CL is obtained for the branching ratio of the $K^+\to\pi^+e^+e^-e^+e^-$ decay, predicted in the Standard Model to be $(7.2\pm0.7)\times 10^{-11}$. Upper limits at 90% CL are obtained at the level of $10^{-9}$ for the branching ratios of two prompt decay chains involving pair-production of hidden-sector mediators: $K^+\to\pi^+aa$, $a\to e^+e^-$ and $K^+\to\pi^+S$, $S\to A^\prime A^\prime$, $A^\prime\to e^+e^-$. The QCD axion is excluded as a possible explanation of the "17 MeV anomaly"., Comment: Version to be submitted to Physics Letters B

Abstract: A sample of $1.3 \times 10^5 K^+ \to \pi^0 e^+ \nu \gamma$ candidates with less than 1% background was collected by the NA62 experiment at the CERN SPS in 2017-2018. Branching fraction measurements are obtained at percent relative precision in three restricted kinematic regions, improving on existing results by a factor larger than two. An asymmetry, possibly related to T-violation, is investigated with no evidence observed within the achieved precision.

Abstract: Measurement of the ultra-rare $K^+\to\pi^+\nu\bar\nu$ decay at the NA62 experiment at CERN requires high-performance particle identification to distinguish muons from pions. Calorimetric identification currently in use, based on a boosted decision tree algorithm, achieves a muon misidentification probability of $1.2\times 10^{-5}$ for a pion identification efficiency of 75% in the momentum range of 15-40 GeV/$c$. In this work, calorimetric identification performance is improved by developing an algorithm based on a convolutional neural network classifier augmented by a filter. Muon misidentification probability is reduced by a factor of six with respect to the current value for a fixed pion-identification efficiency of 75%. Alternatively, pion identification efficiency is improved from 72% to 91% for a fixed muon misidentification probability of $10^{-5}$., Comment: Updated author list and Ref. 4

Abstract: A sample of $2.8 \times 10^4$ $K^{+} \to \pi^{+} \mu^{+} \mu^{-}$ candidates with negligible background was collected by the NA62 experiment at the CERN SPS in 2017--2018. The model-independent branching fraction is measured to be $(9.15 \pm 0.08)\times 10^{-8}$, a factor three more precise than previous measurements.

Abstract: Among the meson decays, K→πνν‾ are the cleanest environment, from the theoretical point of view, where to search for new physics effects. The NA62 Experiment at CERN SPS aims to measure the BR(K+→π+νν‾) with a 10% precision by the end of 2018. It has been commissioned with technical runs in 2014 and 2015, and some preliminary results of the detector performances and quality of data are here reported.

Abstract: A search for heavy neutral lepton (N) production in $K^+\rightarrow\pi^+\nu\bar{\nu}$ decays using the data sample collected by the NA62 experiment at CERN in 2017–2018 is reported. Upper limits of the extended neutrino mixing matrix element $|U_{e4}|^2$ are established at the level of $10^{−9}$ over most of the accessible heavy neutral lepton mass range 144–462 MeV/$c^2$, with the assumption that the lifetime exceeds 50 ns. These limits improve significantly upon those of previous production and decay searches. The $|U_{e4}|^2$ range favoured by Big Bang Nucleosynthesis is excluded up to a mass of about 340 MeV/$c^2$. The NA62 experiment reports an investigation of the $ {K}^{+}\to {\pi}^{+}\nu \overline{\nu} $ mode from a sample of K$^{+}$ decays collected in 2017 at the CERN SPS. The experiment has achieved a single event sensitivity of (0.389 ± 0.024) × 10$^{−10}$, corresponding to 2.2 events assuming the Standard Model branching ratio of (8.4 ± 1.0) × 10$^{−11}$. Two signal candidates are observed with an expected background of 1.5 events. Combined with the result of a similar analysis conducted by NA62 on a smaller data set recorded in 2016, the collaboration now reports an upper limit of 1.78 × 10$^{−10}$ for the $ {K}^{+}\to {\pi}^{+}\nu \overline{\nu} $ branching ratio at 90% CL. This, together with the corresponding 68% CL measurement of ($ {0.48}_{-0.48}^{+0.72} $) × 10$^{−10}$, are currently the most precise results worldwide, and are able to constrain some New Physics models that predict large enhancements still allowed by previous measurements. The NA62 experiment reports an investigation of the $K^+\rightarrow\pi^+\nu\bar{\nu}$ mode from a sample of $K^+$ decays collected in 2017 at the CERN SPS. The experiment has achieved a single event sensitivity of $(0.389\pm 0.024)\times10^{-10}$, corresponding to 2.2 events assuming the Standard Model branching ratio of $(8.4\pm1.0)\times10^{-11}$.

Abstract: The main physics goal of the NA62 experiment at CERN is to precisely measure the branching ratio of the Kaon rare decay K+→π+νν. This decay is strongly suppressed in the Standard Model. On the other hand its branching ratio is calculated with high accuracy. NA62 is designed to measure the K+→π+νν decay rate with an uncertainty better than 10%. The measurement can serve as a probe to some new physics phenomena, which can alter the decay rate. The NA62 experiment has been successfully launched in October 2014. The theory framework as well as the NA62 detector and the preliminary results are reviewed in this article.

Abstract: The NA62 experiment recorded a large sample of $K^+ \rightarrow \mu^+ \nu_{\mu}$ decays in 2007. A peak search has been performed in the reconstructed missing mass spectrum. In the absence of a signal, limits in the range $2 \times 10^{-6}$ to $10^{-5}$ have been set on the squared mixing matrix element $|U_{\mu4} |^2$ between muon and heavy neutrino states, for heavy neutrino masses in the range 300-375 MeV/$c^2$. The result extends the range of masses for which upper limits have been set on the value of $|U_{\mu4} |^2$ in previous production search experiments., Comment: 12 pages, 8 figures.

Abstract: A test of lepton flavour conservation in kaon rare decays by the NA48/2 experiment at CERN SPS is presented. The improved upper limit on the rate of the lepton number violating decay K ± → π ∓ μ ± μ ± is established with the data sample collected in 2003–2004. A precision test of lepton flavour universality in kaon rare decays by the successor NA62 experiment at CERN SPS is reported. The helicity suppressed ratio R K = Γ(K ± → e ± ν )/Γ(K ± → μ ± ν ) is measured with a 0.4% precision using the data sample collected in 2007–2008 and is consistent with the prediction of the Standard Model. The main goal of the NA62 experiment is to measure the branching ratio of the ultra-rare K + → π + ν ν decay with 10% accuracy. This will be achieved by collecting ∼ 1013 K + decays in the fiducial volume. The NA62 estimated sensitivities to rare and forbidden decays of K + and π 0 , including lepton flavour and number violating modes, and the NA62 potential to improve on several experimental limits are discussed.

23. The Charged anti-counter for the NA62 experiment at CERN SPS

Author: Di Filippo, Domenico
Subjects: Physics::Instrumentation and Detectors, High Energy Physics::Experiment, Detectors and Experimental Techniques
Abstract: The NA62 experiment at CERN is intended to measure, with 10% relative error, the Branching Ratio of the K decay $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ which is expected to occur only in about 8 out $10^{11}$ kaon decays. The measurement strategy is to detect the decaying kaon and its product $\pi^{+}$ and to reject all the background channels, which are up to ten orders of magnitude more abundant than the signal, using both kinematical constraints and particle identification systems as veto. The exceptionally low signal yield makes it necessary to prevent also background which is not due to kaon decays, but is rather connected to the interaction of the intense hadron beam with the residual material enconuntered along the decay volume including the beam spectrometer itself: in order to reduce to an acceptable level this last background we designed the Charged Anti Counter (CHANTI). CHANTI is designed to be a compact, efficient and fast response detector to be operated in vacuum and is made up assembling FNAL-NICADD scintillator bars and fast wavelength shifter fibers. It is read out via silicon photomultipliers coupled to fast electronics. It is composed by 6 stations with x-y views and tracking capability; we already constructed 90% of the bars needed, and we characterized more than 50% of them. Finally, the first station was fully assembled and it was tested in the NA62 framework during a testbeam in November 2012. The data collected allowed us to estimate the time resolution of the station, which is a crucial parameter of every veto system. A first MonteCarlo estimation of the amount of the potentially dangerous inelastic interactions was performed showing that it could be a primary source of background, also taking into account the rejection factor ensured by the CHANTI and the other detectors. It is thus indispensable to plan a strategy towards a data-driven estimation of this backgrund source.

Abstract: The NA62 experiment at the CERN SPS is aimed at measuring the branching fraction of the ultrarare decay K+ → π+v with ~10% precision by collecting ~1013 kaon decays in two years of data taking. This amount of data will allow to carry out a wide program of searching for rare and forbidden (within the Standard Model) K+ and π0 decays, including sterile neutrinos, lepton flavor violating modes, exotic particles (e.g. "dark photons"). The expected performances of the NA62 setup will allow to improve existing limits for several decay modes.

Abstract: The NA48/2 and NA62 experiments at CERN study rare kaon decays using the decay in ﬂight technique. In this paper two selected topics will be presented: new measurements performed by the two experiments of the K±→ π±γγ decay which represents a stringent test of the Chiral Perturbation Theory and the measurement of the Branching Ratio of the very rare decay K+→π+νν¯${K^ + } \to {\pi ^ + }\nu \bar \nu $ at 10% level, that will provide a test of the Standard Model and possible extensions beyond it.

Abstract: The NA62 experiment at the CERN SPS reports the first search for $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ using the decay-in-flight technique, based on a sample of $1.21\times10^{11}$ $K^+$ decays collected in 2016. The single event sensitivity is $3.15\times 10^{-10}$, corresponding to 0.267 Standard Model events. One signal candidate is observed while the expected background is 0.152 events. This leads to an upper limit of $14 \times 10^{-10}$ on the $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ branching ratio at 95\% CL., Comment: 18 pages, 13 figures

Abstract: The NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient trigger for decays into electrons in 2007. The kaon beam represents a source of tagged neutral pion decays in vacuum. A measurement of the electromagnetic transition form factor slope of the neutral pion in the time-like region from ∼1 million fully reconstructed π 0 Dalitz decay is presented. The limits on dark photon production in π 0 decays from the earlier kaon experiment at CERN, NA48/2, are also reported.

Abstract: The NA62 experiment collected a large sample of charged kaon decays in 2007 with a highly efficient trigger for decays into electrons. A measurement of the $\pi^0$ electromagnetic transition form factor slope parameter from $1.11\times10^{6}$ fully reconstructed $K^\pm \to \pi^\pm \pi^0_D, \pi^0_D \to e^+ e^-\gamma$ events is reported. The measured value $a = (3.68 \pm 0.57)\times10^{-2}$ is in good agreement with theoretical expectations and previous measurements, and represents the most precise experimental determination of the slope in the time-like momentum transfer region., Comment: 12 pages, 7 figures; Revised version accepted for publication in Physics Letters B

Abstract: Effects of new physics in flavor could be found both in Flavor Changing Neutral Current (FCNC) processes and in Lepton Flavor Violation (LFV) modes. The former offer the possibility to deeply test the standard model in a clean environment, while the latter are sensitive to contribution from several models beyond the standard model. In the Kaon sector both FCNC and LFV will be investigated in the NA62 experiment. In addition the kaons sector is an ideal place where to look for new particles and tiny effects, in the region of hundreds of MeV/ c 2 . In this paper prospects for exotic searches in NA62 will be presented, together with recent results from NA48/2 and NA62-RK on LFV kaon decays modes.

Abstract: The NA62 experiment at CERN SPS aims at measuring-100 events of the very rare decay K + →π + ννˉ (BR∼8.5xlO∼ 10 ). It poses stringent requirements on PID capabilities to reject the overwhelming π + π 0 (63%) and Kμ 2 (21%) backgrounds. The photon veto system must provide a rejection factor of 10∼ 8 on π 0 decays. As a main γ veto detector, the NA48 liquid Kripton calorimeter will be used. To have full geometrical acceptance up to 50 mr, a set of 12 veto stations should be placed along the vacuum decay tank, with an inefficiency 4 in a wide energy range (200 MeV-35 GeV). Good energy resolution (∼10% at 1 GeV) for threshold definition, good time resolution (∼1 ns) to be used at the trigger level, sensitivity to MIP for calibration with muons of the beam halo are needed. A moderate segmentation in the azimuthal angle is desirable, for reducing the counting rate and providing information on the γ direction. We performed an intense R&D program on three solutions: “spaghetti” calorimeter, lead/scintillator sandwich calorimeter, and original re-use of the existing barrel of the OPAL lead-glass e.m. calorimeter. Studies have been performed at the Frascati BTF beam and all three meet the efficiency requirements. The final choice uses a peculiar radial arrangement of lead-glasses in rings. Front-end electronics has been designed to cover the tree orders of magnitude of the signal, contributing to the trigger, and integrated in the general TDAQ, while keeping low cost and simplicity. The first five full veto stations have been constructed. Two tests have been done and problems found fixed. We will discuss about R&D for the technology choice, LAV construction, test beams results and simulation performance.

Abstract: The main goal of the NA62 experiment at CERN is to measure the branching ratio of the ultra-rare K+ →π+ vv decay with 10% accuracy. NA62 will use a 750 MHz high-energy un-separated charged hadron beam, with kaons corresponding to ~ 6% of the beam, and a kaon decay-in-flight technique. The positive identification of kaons is performed with a differential Cherenkov detector (CEDAR), filled with Nitrogen gas and placed in the incoming beam. To stand the kaon rate (45 MHz average) and meet the performances required in NA62, the Cherenkov detector has been upgraded (KTAG) with new photon detectors, readout, mechanics and cooling systems. The KTAG provides a fast identification of kaons with an efficiency of at least 95% and precise time information with a resolution below 100 ps. A half-equipped KTAG detector has been commissioned during a technical run at CERN in 2012, while the fully equipped detector, its readout and front-end have been commissioned during a pilot run at CERN in October 2014. The measured time resolution and efficiency are within the required performances.

Abstract: The NA62 experiment at SPS is a continuation of the long standing CERN kaon physics program. The high statistics and the unprecedent precision allow to probe the Standard Model and test the description of the strong interactions at low energy. The final results on the the lepton universality test by measuring the ratio $R_K = \Gamma(K^{+}\to e^{+}\nu) / \Gamma(K^{+}\to \mu^{+}\nu)$ and the study of the $K^\pm\to\pi^{\pm}\gamma\gamma $ decay are presented. The major goal of the NA62 experiment is to perform a measurement of the $Br(K^{+} \to \pi^{+} \nu \bar{\nu})$ with a precision of 10% in two years of data taking. The detector setup together with the analysis technique is described., Comment: 8 pages, 6 figures, proceedings of the NA62 invited talk at the QCD@Work 2014 workshop

Abstract: The NA62 experiment [1] will measure the BR(K+→π+ν) to within about 10%. To reject the dominant background from final state photons, the large-angle vetoes (LAVs) must detect particles with better than 1 ns time resolution and 10% energy resolution over a very large energy range. A low threshold, large dynamic range, Time-over-threshold based solution has been developed for the LAV front end electronics. Our custom 32 channel 9U board uses a pair of low threshold discriminators for each channel to produce LVDS logic signals. The achieved time resolution obtained in laboratory, coupled to an HPTDC based readout board, is ~ 150 ps.

Abstract: The branching ratio (BR) for the decay K^+ \to \pi^+\nu\bar{\nu} is a sensitive probe for new physics. The NA62 experiment at the CERN SPS will measure this BR to within about 10%. To reject the background from dominant kaon decays with final state photons, the large-angle photon vetoes (LAVs) must detect photons of energy as low as 200 MeV with an inefficiency of less than 10^{-4}. The LAV detectors make use of lead glass blocks recycled from the OPAL electromagnetic calorimeter barrel. We describe the mechanical design and challenges faced during construction, the characterization of the lead glass blocks and solutions adopted for monitoring their performance, and the development of front-end electronics to allow simultaneous time and energy measurements over an extended dynamic range using the time over-threshold technique. Our results are based on test-beam data and are reproduced by a detailed Monte Carlo simulation that includes the readout chain., Comment: LaTeX, 7 pages, 11 attached .eps files.

Abstract: The branching ratio (BR) for the decay K^+ \rightarrow \pi^+ \nu \bar{\nu} is a sensitive probe for new physics. The NA62 experiment at the CERN SPS will measure this BR to within about 10%. To reject the dominant background from channels with final state photons, the large-angle vetoes (LAVs) must detect photons of energy as low as 200 MeV with an inefficiency of less than 10^-4, as well as provide energy and time measurements with resolutions of 10% and 1 ns for 1 GeV photons. The LAV detectors make creative reuse of lead glass blocks recycled from the OPAL electromagnetic calorimeter barrel. We describe the mechanical design and challenges faced during construction, the characterization of the lead glass blocks and solutions adopted for monitoring their performance, and the development of front-end electronics to allow simultaneous time and energy measurements over an extended dynamic range using the time-over-threshold technique.

Abstract: The NA62 experiment at CERN aims at the very challenging task of measuring with 10% relative error the Branching Ratio of the ultra-rare decay K + → π + v , which is expected to occur only in about 8 out of 10 11 kaon decays. This will be achieved by means of an intense hadron beam, an accurate kinematical reconstruction and a redundant veto system for identifying and suppressing all spurious events. In particular, beam induced background, caused by inelastic interactions of the hadron beam with the Si based detector which measures kaon momentum (the so called Gigatracker, GTK) can mimic the signal in case only one pion is detected downstream. To suppress this background we have designed the so called CHarged ANTIcounter (CHANTI) i.e. a series of six guard counters, to be operated in vacuum and covering a wide angular region downstream the last GTK station. CHANTI must have time resolution ∼ 1 ns, must be highly efficient in detecting charged particles and must cope with rates which in the inner part can be some kHz/cm 2 . We have adopted a solution based on triangularly shaped scintillator bars coupled with fast wave–length shifting fibers and individually read by means of Silicon Photomultipliers (SiPM). The full scale prototype of one counter has been built and tested using a prototype front end electronic board which allows fast amplification and individual channel fine bias setting with O(mV) resolution and 0.1% stability. We show first results on the response of the detector to minimum ionizing particles as well as on its time resolution, which are well in line with the specifications.
