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 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 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: 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 Authors, published by EDP Sciences. The NA48/2 experiment at CERN has collected large samples of charged kaons decaying into a pion and two muons for the search of heavy nuetrinos. In addition, its successor NA62 has set new limits on the rate of charged kaon decay into a heavy neutral lepton (HNL) and a lepton, with = e, µ, using the data collected in 2007 and 2015. New limits on heavy neutrinos from kaon decays into pions, muons and positrons are presented in this report.

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: 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 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: 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: 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: 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 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: 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: 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: Looking for phenomena beyond the Standard Model (SM) in rare decays is a complementary approach to direct searches for New Physics (NP) at colliders. One of the theoretically cleanest processes is the ultra rare decay K+ → π+νν. The goal of the NA62 experiment at CERN SPS is to measure the branching ratio (BR) of this decay with 10% precision. The experiment has been launched in 2014. In 2015, the detector was commissioned at a low intensity beam. The experimental setup is described and performances achieved in 2015 are discussed in view of the final measurement.

Abstract: The rare decays K+ --> p+ nu nubar are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness. The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%. Part of the experimental apparatus has been commissioned during a technical run in 2012. The physics prospects and the status of the experiment will be reviewed after the commissioning run of 2014 and the data taking in 2015.

Abstract: A precision lepton universality test by measurement of the helicity suppressed ratio of leptonic decay rates of the charged kaon with ∼ 150000 K ± → e ± ν decays collected by the NA62 experiment in 2007-08 is presented. The record accuracy of 0.4% constrains the parameter space of new physics models with extended Higgs sector, a fourth generation of quarks and leptons or sterile neutrinos.An improved upper limit on the rate of the lepton number violating decay K ± → π ∓ μ ± μ ± , which probes the resonant enhancement of the rate in the presence of heavy Majorana neutrinos in the ∼ 100 MeV range, is presented.The rare decays K + → π + νν are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness. The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%.

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: 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: A measurement of the direct CP violating charge asymmetries of the Dalitz plot linear slopes $A_g=(g^+-g^-)/(g^++g^-)$ in $K^\pm\to\pi^\pm\pi^+\pi^-$ and $K^\pm\to\pi^\pm\pi^0\pi^0$ decays by the NA48/2 experiment at CERN SPS is presented. A new technique of asymmetry measurement involving simultaneous $K^+$ and $K^-$ beams and a large data sample collected allowed a result of an unprecedented precision. The charge asymmetries were measured to be $A^c_g=(-1.5\pm2.2)\times10^{-4}$ with $3.11\times 10^9$ $K^{\pm}\to\pi^\pm\pi^+\pi^-$ decays, and $A^n_g=(1.8\pm1.8)\times10^{-4}$ with $9.13\times 10^7$ $K^{\pm}\to\pi^\pm\pi^0\pi^0$ decays. The precision of the results is limited mainly by the size of the data sample.

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: The Kaon physics program at CERN and in Europe will be presented. I will first give a short review of recent results form the NA48/2 and NA62 experiments, with special emphasis to the measurement of RK , the ratio of Kaon leptonic decays rates, K → eν and K → μν, using the full minimum bias data sample collected in 2007-2008. The main subject of the talk will be the study of the highly suppressed decay K → πνν. While its rate can be predicted with minimal theoretical uncertainty in the Standard Model (BR ∼ 8 × 10−11), the smallness of BR and the challenging experimental signature make it very difficult to measure. The branching ratio for this decay is thus a sensitive probe of the flavour sector of the SM. The aim of NA62 is the measurement of the K → πνν BR with ∼ 10% precision in two years of data taking. This will require the observation of 10K 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 flavour and/or number violating K decays. Data taking will start in October 2014. The physics prospects and the status of the construction and commissioning of the NA62 experiment will be presented. In the last part of the talk I will report on Kaon physics results and prospects from other experiments at CERN (e.g. LHCb) and in Europe (e.g. KLOE and KLOE-2) and briefly mention the status in US.

Abstract: Events with a large rapidity gap in deep inelastic scattering with Q2 greater-than-or-equal-to 10 GeV2 have been studied in the ZEUS detector. The properties of these events with W > 140 GeV are consistent with a leading twist diffractive production mechanism. In the laboratory frame, with E(T)jet greater-than-or-equal-to 4 GeV, 15% of the events are of the 1-jet type with negligible 2-jet production. The single jet is back-to-back in azimuth with the scattered electron. No energy flow is observed between the jet and the proton direction. With a lower jet transverse energy cut 2-jet production is observed both in the laboratory and the gamma*p centre-of-mass systems, demonstrating the presence of hard scattering in the virtual photon proton interactions that give rise to large rapidity gap events.

The NA62 collaborations aims to measure the decay [Formula: see text] with an uncertainty of 10% or better. The NA62 detector and preliminary results from a pilot run in 2014 are presented. In addition, recent results of the NA48/2 collaboration are reported. A search for Dark Photons has been performed in [Formula: see text] decays via the kaon decays [Formula: see text] and [Formula: see text]. No dark photon signal was observed and new upper limits on the mixing parameter [Formula: see text] and the dark photon mass were computed. We also report the first observation of the kaon decay [Formula: see text].

Abstract: The new published measurements of the K ± → π ± γ γ decay with minimum bias data samples collected by the two experiments NA48/2 and NA62 are discussed. The results include a model independent decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description. The model independent branching ratio in the kinematic range z = ( m γ γ / m K ) 2 > 0.2 , obtained by combining the NA48/2 and NA62 results, is B M I = ( 0.965 ± 0.63 ) × 10 − 6 . The combined branching ratio in the full kinematic range assuming a ChPT description is B C h P T = ( 1.003 ± 0.056 ) × 10 − 6 . The uncertainties are dominated by the statistical errors. The data support the ChPT prediction for a cusp in the di-photon invariant mass spectrum at the two pion threshold and are in agreement with both O ( p 4 ) and O ( p 6 ) ChPT predictions.

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: 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 main goal of the NA62 experiment at the CERN SPS accelerator is to measure the branching fraction of the ultra-rare decay K+→π+ν with 10% accuracy. Key aspects of the detector configuration are described, with emphasis on tagging and timestamping the minority kaons in the high intensity, unseparated, charged-particle beam using KTAG, an upgraded version of a CEDAR differential Cherenkov detector. Data are presented showing that KTAG was successfully commissioned at CERN in November 2012.

Abstract: A precision measurement of the ratio of the rates of kaon leptonic decays KÂ± â eÂ± v and KÂ± â I¼Â±v with the full minimum bias data sample collected with low intensity 75 GeV/c beam by the NA62 experiment at CERN in 2007-2008 is reported. The result, obtained by analyzing 150,000 reconstructed K Â± â eÂ± v candidates with 11% background contamination, has a record precision of 0.4% and is in agreement with the Standard Model expectation. An improved upper limit on the rate of the lepton number violating decay KÂ± â I Â±I¼ Â±I¼Â± from the NA48/2 experiment, which probes the resonant enhancement of the rate in the presence of heavy Majorana neutrinos in the 100 MeV range, is also reported. The prospects for the searches of lepton number and flavour violating decays of the charged kaon with an improved sensitivity down to 10-12 during the forthcoming main phase of the NA62 experiment are discussed.

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: We report the results from a study of the full sample of ~ 6.031 10^7 K+- -> pi+- pi0 pi0 decays recorded by the NA48/2 experiment at the CERN SPS. As first observed in this experiment, the pi0 pi0 invariant mass M00 distribution shows a cusp-like anomaly in the region around M00 = 2m+, where m+ is the charged pion mass. This anomaly has been interpreted as an effect due mainly to the final state charge exchange scattering process pi+ pi- -> p0 p0 in K+- -> pi+- pi+ pi- decay. Fits to the M00 distribution using two different theoretical formulations provide the presently most precise determination of (a0 - a2), the difference between the pi pi S-wave scattering lengths in the isospin I=0 and I=2 states. Higher-order pi pi rescattering terms, included in the two formulations, allow also an independent, though less precise, determination of a2., Comment: 19 pages, 12 figures
