The Ring Imaging Cherenkov detector is crucial for the identification of charged particles in NA62 experiment at CERN SPS. commissioning was completed 2016 by precise alignment mirrors using reconstructed tracks. procedure and measurement basic performance are described. radius resolution, ring centre single hit resolution mean number hits per evaluated positron contribution residual mirror misalignment to calculated.
Abstract The NA62 experiment at CERN utilises a differential Cherenkov counter with achromatic ring focus (CEDAR) for tagging kaons within an unseparated monochromatic beam of charged hadrons. CEDAR-H detector was developed to minimise the amount material in path by using hydrogen gas as radiator medium. shown satisfy kaon requirements test-beam before installation and commissioning experiment. performance measured data collected 2023.
A large RICH detector is used in NA62 to suppress the muon contamination charged pion sample by a factor of 100 momentum range between 15 and 35 GeV/c. Cherenkov light collected 1952 photomultipliers placed at upstream end.

Recent results from searches for rare kaon decays with the NA62 experiment at CERN are reported, together future prospects. A HIKE, to go beyond NA62, has been proposed push physics an unprecedented frontier. The HIKE timescale and expected performance described. Among results, measurement of branching ratios flavour changing neutral current $K^+\rightarrow\pi^+\mu^+\mu^-$ radiative non leptonic $K^+\rightarrow\pi^+\gamma\gamma$ upper limits given lepton flavor number violating...
In this paper we describe the NA62 experiment, which is a fixed target experiment at CERN SPS who aims measuring Branching Ratio of K + → π ν ν̄ but also to study other rare kaon decays. Important results such as advances in ν̄, search for heavy neutral leptons and lepton number violating decays will be shown.
The NA62 experiment at the CERN SPS recorded in 2007 a large sample of $K^+ \rightarrow \mu^+ \nu_\mu $ decays. A peak search missing mass spectrum this decay is performed. In absence observed signal, limits obtained on $\mathcal{B}(K^+ \nu_h )$ and mixing matrix element $|U_{\mu4}|$ are reported. upgraded started data taking 2015. About 5$\times 10^{11} K^+$ decays have been so far to measure branching ratio \pi^+ \nu\overline{\nu}$ decay. Preliminary results from analysis based about 5$\%$...
In this paper we present new results on upper limits for the search of Heavy Neutral Leptons (HNL) with data collected by NA48/2 (2003-2004), NA62-RK (2007) and NA62 (2015) CERN experiments. The different trigger configuration allow to both long short living heavy neutrinos in mass range below kaon mass. addition status K + → π v detector will be briefly presented.
The NA62 experiment at the CERN SPS is designed to conduct precision tests of Standard Model by studying rare decays charged kaons. took data in 2016-2018 and collected a large sample kaon into final states with multiple particles. sensitivity range lepton flavour number violating provided this set improved over previously reported measurements.
