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: 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 PADME collaboration aims to search for signals of a light dark photon A′ using the beam of the LNF LINAC. The experiment, approved by INFN at the end of 2015, foresees to detect A′, produced in the annihilation of positrons on a thin fixed target, by searching for missing mass signals. The detector construction is ongoing and should be completed within the end of 2017 in order to allow the collection of about 1013 positrons on target which are necessary to get a 10−3 sensitivity on the mixing parameter ε up to a dark photon mass of 23.7 MeV/c2.

Abstract: The PADME experiment, at the Laboratori Nazionali di Frascati (LNF) of INFN, is designed to be sensitive to the production of a low mass gauge boson A ′ of a new U ( 1 ) symmetry holding for dark particles. The DA Φ NE Beam-Test Facility of LNF is providing a high intensity, mono-energetic positron beam impacting on a low Z target to provide e + e − annihilations, where the dark photon can be produced along with an ordinary photon. Simulation studies predict a sensitivity on the interaction strength ( e 2 parameter) down to 10−6, in the mass region 1 MeV/ c 2 M A ′ 23.7 MeV/ c 2 , for one year of data taking with a 550 MeV beam. In 2018 the first run will take place, and early data will give the opportunity to compare the detector performance with the design parameters. Right now, an intense activity is taking place to install and commission the PADME experimental apparatus on site.

Abstract: The PADME experiment is under construction at the Frascati National Laboratories of INFN to explore the coupling between ordinary and dark matter. This will be done through the detection of Standard Model photons produced in the reaction e + e − → γ A ′ . The measurement of the photons 4-momentum allows to reconstruct the missing mass spectrum of this process, where the A ′ could appear as a peak. To this purpose, two independent electromagnetic calorimeters are used. The layout of the two detectors, and their expected performance measured during prototypes tests, are here 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: PADME (Positron Annihilation into Dark Matter Experiment) is an experiment that will search for the production of a dark photon A ′ from the annihilation of a positron beam on a thin diamond target. It will use the 550 MeV positron beam of the Beam Test Facility (BTF) of the Laboratori Nazionali di Frascati (LNF) of INFN. According to the PADME design, the region of sensitivity is M A ′ ≤ 23.7 MeV/c 2 and ϵ 2 > 1 0 − 6 , where M A ′ and ϵ are the dark photon mass and the A ′ γ mixing parameter. This paper presents the status of the active diamond target, in particular the assembly of two 32 channel targets of polycrystalline Chemical Vapor Deposition (CVD) diamond, one with graphitic strips and another with traditional CrAu strips.

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: The PADME experiment, hosted at the Laboratori Nazionali di Frascati in Italy, is dedicated to the dark photon search. It looks for the reaction $e^{+}\,e^{-}\rightarrow A'\,\gamma$, where $A'$ indicates the dark photon. The $550\,\text{MeV}$ positrons beam that impinges on electrons, coming from an active diamond target, allows to scan $A'$ masses up to $23.7\,\text{MeV}$. In this context, the segmented electromagnetic calorimeter plays a fundamental role, since it measures the final photon four-momentum. It consists of $616$ BGO crystals displaced in a cylindrical shape of $\approx29\,\text{cm}$ radius with a central square hole of $5$ crystals side, to let Bremsstrahlung radiation pass, to limit the calorimeter trigger rate. Each crystal is read by a HZC XP1911 type B photomultipliers and their signal is digitised by means of a CAEN V1742 board, taking $1024$ samples at $1\,\text{GS/s}$. Here we report in detail the solutions adopted for the calorimeter together with the results obtained in tests performed on a small prototype and on single scintillating units., Comment: 10 pages, 9 figures

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: © 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: $K^+ \rightarrow \pi^+ \nu \bar{\nu}$ 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 KLOE experiment at the ϕ – factory DAΦNE in Frascati near Rome is the first to have employed Initial State Radiation (ISR) to precisely determine the e + e − → π + π − ( γ ) cross section below 1 GeV. Such a measurement is particularly important to test the Standard Model (SM) calculation for the ( g − 2 ) of the muon, where a long standing 3 σ discrepancy is observed. In 2005 and 2008 KLOE published two measurements of the π + π − cross section with the photon emitted at small angles, and an independent measurement of the π + π − cross section with the photon emitted at large angles using data at a collision energy of 1 GeV (i.e., 20 MeV below the ϕ -peak) was published in 2010. While the measurements were normalized to the DAΦNE luminosity using large angle Bhabha scattering, a new analysis has been performed which derives the pion form factor directly from measuring the bin-by-bin π + π − γ / μ + μ − γ ratio. We present the preliminary results of this new measurement, as well as the previously published ones, and the impact on the evaluation of the hadronic contribution to the muon anomaly.

Abstract: The NA62 experiment at CERN SPS is aimed to measure the branching ratio of the ultra-rare decay $K^+\rightarrow\pi^+ \nu \bar{\nu}$ with 10\% accuracy. The experiment operates with a 75 GeV/c high intensity (750 MHz) secondary beam. A new detector, named Charged Particle Hodoscope (CHOD), designed to produce an input signal to the L0 trigger processor for events with charged particles produced in kaon decays, has been assembled, installed, integrated in NA62 Data Acquisition System (DAQ) and commissioned in 2016. During the whole 2016 run the detector has been in continuous operation. Design and performance features of the detector are presented., Comment: INSTR2017 conference

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 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: 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: 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: 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: KLOE uses the radiative return to measure the hadronic cross section e(+)e(-) --> pi(+) pi(-) at DAPhiNE. The emission of one or more hard photons in the initial state (ISR) reduces the collision energy, otherwise fixed at 1020 MeV, and allows to perform an effective scan of the two pions invariant mass squared, s(pi), in the whole s(pi) region 2 from threshold to m.. An extremely accurate knowledge of experimental systematics, background, luminosity and, on the theoretical side, a precise description of initial state radiation are needed to perform a competitive measurement. We present here the status of the analysis of 140 pb(-1) collected in 2001. A preliminary evaluation of the hadronic contribution to a(mu) in the S-pi range between 0.37 GeV2 and 0.93 GeV2 yields a(mu) = 378.4 +/- 0.8(stat) +/- 4.5(syst) +/- 3-0(theo) 3.8(FSR), consistent with the CMD-2 result and confirming the present discrepancy between e(+)e(-) and tau data.

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: Neutral kaons produced in correlated pairs at a phi-factory offer unique possibilities to perform fundamental tests of CPT invariance, as well as of the basic principles of quantum mechanics. The analysis of the data collected by the KLOE experiment at DAFNE is still ongoing with the aim of improving previous results and limits on several parameters describing CPT violation and decoherence. Ancillary measurements like the regeneration cross section on the beam pipe materials are also in progress and will be very useful to reduce the systematic uncertainties. Prospects on improvements at the KLOE-2 experiment, aiming at an increase of the integrated luminosity of about a factor of ten with an upgraded detector, will be also discussed., Comment: 8 pages, 6 figures

Abstract: The KLOE experiment has collected an integrated luminosity of about 2.5 fb−1 at the φ factory DAφNE. φ radiative decays have been used to investigate the properties of the light scalar mesons f0(980)/a0(980), whose structure is still controversial.A direct search of σ(600)→π0π0 decay has been performed with data taken at 1 GeV, where φ decays are suppressed.The whole KLOE data set includes also 100 million η’s produced through the radiative decay φ→ηγ and tagged by means of the monochromatic recoil photon. From this sample we have investigated η decays relevant to test ChPT predictions. We present published and preliminary results achieved from full statistics.

Abstract: The data collected by the KLOE Collaboration at the Frascati -factory DAΦ from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons a0(980) and f0 (980) into two pseudoscalar mesons have been exploited to measure the relevant parameters of those resonances. The radiative decays → ηγ and η'γ have been used for the determination of the pseudoscalar mixing angle and to search for a possible gluonium content in the η'. The dynamics of the η → 3π decay has been studied and the Dalitz Plot parameters have been measured. The large amount of η mesons produced allowed also to study interesting rare η decays.

Abstract: The most precise determinations of Vus comes from semileptonic kaon decays. The KLOE experiment at DAΦNE the Frascati φ factory , has measured all the experimental inputs to Vus for both neutral and charged kaons. Preliminary results for BR(K ± ! π 0 e ± ν) and BR(K ± ! π 0 μ ± ν), and for τ± are presented, together with measurements of the KLe3 and KL μ 3 decay BR, the KSe3 decay BR and the KL lifetime τ L. From our results for the 5 branching ratios and τ L we find Vus=0.2258±0.0022. We have also measured the fully inclusive K + μ 2 ( γ) absolute branching ratio for which we obtain BR(K + ! μν ( γ))=0.6366±0.0017. Combining this value with recent lattice results for fK/ f π gives Vus=0.2223±0.0026.

Abstract: The KLOE experiment has just collected 2.5 fb−1 of e + e − collisions at center of mass energy around the φ mass. Radiative decays are used to produce large statistical samples of light scala and pseudoscalar mesons. The analysis of the first 450 pb−1 is almost completed. For the scala sector we have investigated the properties of these particles by studying their invariant mass shapes or the event density in the Dalitz plot. With the same data set, the η mass and the ratio BR(φ → η′γ)/BR(φ → ηγ) have been measured. From this last quantity we extract the most precise determination of the η/η′ mixing angle, which is strictly related to the η′ gluon content.

Abstract: The KLOE experiment, running at the Frascati DAΦNE φ‐factory since 1999, was designed to measure the R(e′/e) ratio to an accuracy of few 10−4. However, its physics program is wider than CP violation, covering both kaon and non‐kaon physics items. During the year 2000 data taking, ∼ 20 pb−1 were collected and a total integrated luminosity of 200 pb−1 is expected by the end of 2001. A wealth of measurements can be addressed with these data and a number of preliminary results have been already obtained using the year 2000 statistics, in particular on rare KS decays. After a brief description of the detector, the KS tagging technique is discussed. Preliminary measurements of BR(KS → π+π−)/BR(KS → π0π0) and BR(KS → πev) are then presented. Finally, the perspectives for future analyses are discussed.

Abstract: To search for the production of a dark photon ($A^{\prime} $) in the process ${e}^{+}{e}^{-}\to A^{\prime} \gamma $, the PADME apparatus has been built athe INFN Laboratori Nazionali di Frascati. It is a small-scale detector consisting of an active target, a beam monitor system, a spectrometer to measure charged particle momenta in the range 50–400 MeV, a dipole magnet to deflect the primary positron beam out of the spectrometer and allow charged particle momentum analysis and an electromagnetic calorimetric system to detect signal and background photons produced in the annihilations with high accuracy. Each element has specific requirements that are stringent and sometimes at the limit of present technology. This proceeding will give an overview of each component and a description of the technical solutions implemented to accomplish the experiment needs. Results of the commissioning data taking, performed from October 2018 to February 2019, will be illustrated.

Abstract: A search for heavy neutral lepton production in $K^+$ decays using a data sample collected with a minimum bias trigger by the NA62 experiment at CERN in 2015 is reported. Upper limits at the $10^{-7}$ to $10^{-6}$ level are established on the elements of the extended neutrino mixing matrix $|U_{\ell 4}|^2$ ($\ell=e,\mu$) for heavy neutral lepton mass in the range $170-448~{\rm MeV}/c^2$. This improves on the results from previous production searches in $K^+$ decays, setting more stringent limits and extending the mass range., Comment: Version accepted for publication in Phys.Lett.B (12/01/2018)

Abstract: The NA62 experiment recorded a large sample of K+→μ+νμ 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 2×10−6 to 10−5 have been set on the squared mixing matrix element |Uμ4|2 between muon and heavy neutrino states, for heavy neutrino masses in the range 300–375 MeV/ c2 . The result extends the range of masses for which upper limits have been set on the value of |Uμ4|2 in previous production search experiments.

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: 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: 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.
