K+ → π+ ν ν sensitivity at NA62 with the 2016 data — •Radoslav Marchevski — Johannes Gutenberg University, Mainz, Germany
NA62 is a fixed target experiment at CERN, which operates since 2015 on the 400 GeV proton beam supplied by the CERN SPS accelerator. The main physics task of the experiment is a precise measurement of the rare kaon decay K+ → π+ν ν using a decay-in-flight technique. In the Standard Model this channel is strongly suppressed to O(10−10) and therefore is very sensitive to new physics, which could modify the decay rate. To measure this rare decay the experiment has to achieve a challenging background suppression of 1012. The background rejection capabilities as well as the sensitivity using the 2016 data will be presented.
