Abstract: The NA62 experiment reports the branching ratio measurement $BR(K^+\to\pi^+\nu\bar\nu)$ at 68% CL, based on the observation of 20 signal candidates with an expected background of 7.0 events from the total data sample collected at the CERN SPS during 2016-2018. This provides evidence for the very rare $K^+\to\pi^+\nu\bar\nu$ decay, observed with a significance of $3.4\sigma$. The experiment achieves a single event sensitivity of $(0.839\pm0.054)\times10^{-11}$, corresponding to 10.0 events assuming the Standard Model branching ratio of $(8.4\pm1.0)\times10^{-11}$. The result represents the most accurate measurement achieved so far of this ultra-rare decay. Future prospects and plans for data taking from 2021 will also be presented.

Abstract: The NA62 experiment at CERN collected a large sample of charged kaon decays into ﬁnal states with multiple charged particles in 2016-2018. This sample provides sensitivities to rare decays with branching ratios as low as 10 −11 . Searches for the lepton number violating $K^{+} \to \pi ^{-}\mu ^{+}e^{+}$ decay and the lepton ﬂavour violating $K^{+} \to \pi ^{+}\mu ^{-}e^{+}$ and $\pi ^{0} \to \mu ^{-}e^{+}$ decays are reported. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% conﬁdence level. These results improve by one order of magnitude over previous results for these decay modes.

Abstract: The NA62 experiment at CERN reports searches for $K^+ \to e^+ N$, $K^+ \to \mu^+ N$ and $K^+ \to \mu^+ X$ 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 $O(10^{-9})$ and $O(10^{-8})$ on the neutrino mixing parameter $|U_{e4}|^2$ and $|U_{\mu 4}|^2$, improving on the earlier searches for heavy neutral lepton production and decays in the kinematically accessible mass range. 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 $O(10^{-5})$ to $O(10^{-7})$. An upper limit of $1.0 \cdot 10^{-6}$ is established at 90\% CL on the $K^+\to \mu^+ \nu \nu \bar{\nu}$ branching fraction.

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 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 NA62 experiment at CERN offers the highest experimental sensitivity to rare and forbidden kaon decays. A search for lepton number violating processes K+→π-e+e- and K+→π-μ+μ+, using a partial data set collected by NA62 in 2016-2018, is reported. No signals are observed and upper limits at 90% confidence level on the branching fractions of these decays are obtained: 2.2x10-10 and 4.2x10-11, respectively. These results improve on previously reported measurements by factors of 3 and 2, respectively.

Abstract: The decay $K^{+} \to \pi^{+} \nu \bar{\nu}$, 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 $K^{+} \to \pi^{+} \nu \bar{\nu}$ with a decay-in-flight technique, novel for this channel. The statistics of the first sample collected with the full detector, in 2016, allows to reach the Standard Model sensitivity for $K^{+} \to \pi^{+} \nu \bar{\nu}$, entering the domain of $10^{-10}$ single event sensitivity and showing the proof of principle of the experiment. The preliminary result from the 2016 data set is presented.

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: The high-intensity setup, trigger system flexibility and detector performance make the NA62 experiment at CERN particularly suitable to perform direct searches for long-lived hidden-sector particles, such as dark photons, dark scalars, axion-like particles, and heavy neutral leptons, using kaon and pion decays as well as operating the experiment in dump mode. Results from NA62 will be presented on a search for $π^0$ decays to one photon and an invisible massive dark photon. From about 400 M $π^0$ decays, no signal is observed beyond the expected fluctuation of the background and limits are set in the plane of the dark photon coupling to ordinary photon versus the dark photon mass. The analysis has been also interpreted in terms of the branching ratio for the electroweak decay $π^0 → γνν^¯$.

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: The first observation of the $K^\pm → π^\pm π^0 e^+ e^-$ rare decay by the NA48/2 experiment at CERN SPS is reported, based on $∼2\times 10^{11} K^\pm$ decays recorded in 2003-2004. From a sample of 4919 candidates with 4.9% background the branching ratio in the full kinematic region is measured to be BR($K^± → π^± π^0 e^+ e^-) = (4.24\pm 0.14)\times 10^-6$.The study of the kinematic space shows evidence for a structure dependent contribution in agreement with predictions based on Chiral Perturbation Theory. The CP-violating asymmetry between $K^\pm → π^+ π^0 e^+ e^-$ and $K^- → π^- π^0 e^+ e^-$ decay rates has been measured, providing an upper limit $|A_{CP}| < 4.82 \times 10^{-2}$ at 90% CL.The NA48/2 combined measurement of the charged kaon semileptonic form factors, based on 4.4 million $K^\pm → π^0 e^± ν_e$ and 2.3 million $K^\pm → π^0 μ^\pm ν_μ$ events collected in 2004, is presented. This result represents the most precise form factor measurement from a combined $K_{l3}^{\pm}$ analysis.

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: 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: 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: 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: © 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 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 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 NA62 experiment at CERN collected a large sample of charged kaon decays in ight with a minimum bias trigger in 2007. Upper limits on the rate of the charged kaon decay into a muon and a heavy neutral lepton (HNL) obtained from this data are reported for a range of HNL masses. The NA62 experiment has collected further data in 2015 with a completely new and improved detector. New limits on heavy neutrinos from kaon decays into electron and HNL will be presented.

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.

Abstract: The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(+-) ($K^\pm \to \pi^+ \pi^- e^\pm \nu$) and Ke4(00) ($K^\pm \to \pi^0 \pi^0 e^\pm \nu$) with nearly one percent background contamination. The detailed study of form factors and branching rates, based on these data, has been completed recently. The results brings new inputs to low energy strong interactions description and tests of Chiral Perturbation Theory (ChPT) and lattice QCD calculations. In particular, new data support the ChPT prediction for a cusp in the $\pi^0\pi^0$ invariant mass spectrum at the two charged pions threshold for Ke4(00) decay. New final results from an analysis of about 400 $K^\pm \to \pi^\pm \gamma \gamma$ rare decay candidates collected by the NA48/2 and NA62 experiments at CERN during low intensity runs with minimum bias trigger configurations are presented. The results include a model-independent decay rate measurement and fits to ChPT description., Comment: XIIth International Conference on Heavy Quarks and Leptons 2014, Mainz, Germany

Abstract: Recent results and prospects for precision tests of the Standard Model in kaon decay-in-flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged kaon at the level of 0.4% precision constrains the parameter space of new physics models with extended Higgs sector, a fourth generation of quarks and leptons or sterile neutrinos. Searches for heavy neutrino mass states and the dark photon in the ∼ 100 MeV/c(2) mass range based on samples collected in 2003-2007 are in progress and prospects will be discussed. The NA62 experiment, starting in 2014, will search for a range of lepton number and lepton flavour violating decays of the charged kaon and the neutral pion at improved sensitivities down to ∼ 10(-12), which will probe new physics scenarios involving heavy Majorana neutrinos or R-parity violating SUSY.

Abstract: A sample of $4.687\times 10^6$ fully reconstructed $K^\pm\to\pi^\pm\pi^0_D$, $\pi^0_D\to\gamma e^+e^-$ decay candidates in the kinematic range $m_{ee}>10~{\rm MeV}/c^2$ with a negligible background contamination collected by the NA48/2 experiment at CERN in 2003-04 is analysed to search for the dark photon ($A'$) via the decay chain $K^\pm\to\pi^\pm\pi^0$, $\pi^0\to\gamma A'$, $A'\to e^+e^-$. No signal is observed, and preliminary exclusion limits on space of dark photon mass $m_A'$ and mixing parameter $\varepsilon^2$ are reported., Comment: Talk given at the DHF 2014 conference, Messina, Italy, 24-26 September 2014

Abstract: A sample of 65210 $K^\pm \rightarrow \pi^0 \pi^0 e^\pm \nu $ ($K_{e4}^{00}$) decay candidates with $1\%$ background contamination has been collected in 2003--2004 by the NA48/2 collaboration at the CERN SPS. A study of the differential rate provides the first measurement of the hadronic form factor variation in the plane $(M_{\pi\pi}^2 ,M_{e\nu}^2)$ and brings evidence for a cusp-like structure in the distribution of the squared $\pi^0\pi^0$ invariant mass around $4m_{\pi^+}^2$. Exploiting a model independent description of this form factor, the branching ratio, inclusive of radiative decays, is obtained using the $K^\pm \rightarrow \pi^0 \pi^0 \pi^\pm $ decay mode as normalization. It is measured to be BR$(K_{e4}) = (2.552 ± 0.010_{stat} \pm 0.010_{syst} \pm 0.032_{ext}) \times 10^{−5}$ which improves the current world average precision by an order of magnitude while the $1.4\%$ relative precision is dominated by the external uncertainty from the normalization mode. A comparison with the properties of the corresponding mode involving a $\pi^+ \pi ^-$ pair ($K_{e4}^{+-}$) is also presented. A sample of 65210 $\mathrm{K^{\pm}} \rightarrow \pi^{0} \pi^{0} \mathrm{e^{\pm}} \nu$ ($\mathrm{K}_{\mathrm{e}4}^{00}$) decay candidates with $1\%$ background contamination has been collected in 2003$-$2004 by the NA48/2 collaboration at the CERN SPS.

Abstract: The NA48/2 Collaboration at CERN has accumulated and analysed unprecedented statistics of rare kaon decays in the $K_{e4}$ modes: $K_{e4}(+-)$ ($K^\pm \to \pi^+ \pi^- e^\pm \nu$) and $K_{e4}(00)$ ($K^\pm \to \pi^0 \pi^0 e^\pm \nu$) with nearly one percent background contamination. It leads to the improved measurement of branching fractions and detailed form factor studies. New final results from the analysis of 381 $K^\pm \to \pi^\pm \gamma \gamma$ rare decay candidates collected by the NA48/2 and NA62 experiments at CERN are presented. The results include a decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description., Comment: Prepared for the Proceedings of "Moriond QCD and High Energy Interactions.

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 decay K+→π+νν¯ is highly suppressed in the Standard Model (SM), while its rate can be predicted with minimal theoretical uncertainty. The branching ratio (BR) for this decay is thus a sensitive probe of the flavor sector of the SM; its measurement, however, is a significant experimental challenge. The primary goal of the NA62 experiment is to measure BR(K+→π+νν¯) with ∼10% precision. This will require the observation of 1013 K+ decays in the experiment's fiducial volume, as well as the use of high-performance systems for precision tracking, particle identification, and photon vetoing. These aspects of the experiment will also allow NA62 to carry out a rich program of searches for lepton flavor and/or number violating K+ decays. Part of the experimental apparatus was commissioned during a technical run in 2012; installation continues and data taking is expected to begin in late 2014. The physics prospects and the status of the NA62 experiment are reviewed.

Abstract: In 2007 the NA62 experiment at CERN collected a large sample of charged kaon decays with a highly efficient trigger selecting events with electrons in the final state. The kaon beam represents a rich source of tagged neutral pion decays in vacuum. The electromagnetic transition form factor slope of the π(0) in the time-like region has been measured from about 10(6) fully reconstructed π(0) Dalitz decays collected in 2007. The preliminary result a = (3.68 ± 0.51(stat) ± 0.25(syst)) × 10(-2) is the most precise to date. This value is compatible with theoretical expectations and consistent with the previous measurements.

Abstract: A sample of more than one million $K^{\pm} \rightarrow \pi^{+} \pi^{-} e^{\pm} \nu$ ($K_{e4}$) decay candidates with less than one percent background contamination has been collected by the NA48/2 experiment at the CERN SPS in 2003--2004, allowing a detailed study of the decay properties. The branching ratio, inclusive of $K_{e4\gamma}$ decays, is measured to be BR$(K_{e4}) = (4.257 \pm 0.016_{exp} \pm0.031_{ext}) \times 10^{-5}$ with a total relative error of 0.8%. This measurement complements the study of S- and P-wave hadronic form factors by assigning absolute values to the relative hadronic form factors obtained earlier in a simultaneous analysis of the $\pi\pi$ scattering lengths conducted on the same data sample. The overall form factor normalization $f_s = 5.705 \pm 0.017_{exp} \pm 0.031_{ext}$ is obtained with a total relative precision of 0.6%.
