/NA62
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 data collected with different trigger configuration allow to search for both long and short living heavy neutrinos in the mass range below the kaon mass. [...]

/NA62
K→πvˉv 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+→π+vˉv decay with 10% precision. [...]

Performance and operation of the calorimetric trigger processor of the NA62 experiment at CERN SPS
/ Ammendola, R (Rome U., Tor Vergata) ; Barbanera, M (Pisa U. ; INFN, Pisa) ; Battista, D (Rome U., Tor Vergata) ; Bizzarri, M (Perugia U.) ; Bonaiuto, V (Rome U., Tor Vergata) ; Ceccucci, A (CERN) ; Checcucci, B (INFN, Perugia) ; Simone, N De (CERN) ; Fantechi, R (CERN) ; Federici, L (Rome U., Tor Vergata ; INFN, Rome2) et al.
The NA62 experiment at the CERN SPS aims at measuring the branching ratio of the very rare kaon decay K+→π+νˉν (expected 10−10) with a 10% background. Since an high-intensity kaon beam is required to collect enough statistics, the Level-0 trigger plays a fundamental role in both the background rejection and in the particle identification. [...]

The NA62 experiment at the CERN SPS aims at measuring the branching ratio of the very rare kaon decay K(+) → π(+) ν bar nu (expected 10(−)(10)) with a 10% background. Since an high-intensity kaon beam is required to collect enough statistics, the Level-0 trigger plays a fundamental role in both the background rejection and in the particle identification. [...]

The goal of the NA62 experiment at the CERN SPS is the measurement of the Branching Ratio of the very rare kaon decay K(+)→π(+) ν bar nu with a 10% accuracy by collecting 100 events in two years of data taking. An efficient photon veto system is needed to reject the K(+)→π(+) π(0) background and a liquid krypton electromagnetic calorimeter will be used for this purpose in the 1-10 mrad angular region. [...]
