Abstract
NA62 is a high-energy physics experiment located at the CERN SPS. NA62 aims at measuring the ultra-rare decay K+ → π+ν¯ ν with a 10% precision. The K+ → μ+ν decay is the main background which needs to be suppressed by a factor 2×1012. This goal can be achieved by kinematical cuts, different stopping power of μ+/π+ and a RICH detector able to measure particles velocity in a momentum range between 15 and 35GeV/c. Moreover, the RICH detector measures the pion crossing time with a resolution of 100ps and produces the L0 trigger for a charged track. In this paper the NA62 RICH will be described, and the preliminar results regarding pion/muon separation in the 2015 data taking will be presented.
