Status and latest results from the NA62 Experiment at CERN

The ultra-rare decays K→πνν¯ are excellent processes to make tests of new physics at the highest energy scale complementary to LHC, thanks to their theoretically clean predictions. The NA62 experiment at the CERN SPS aims to collect about 100K+→π′νν¯ events in two years of data taking, keeping the background at 10% level. A rich physics program is accessible to NA62, in addition to the main goal. A precise measurement of the helicity-suppressed ratio RK of the K±→eve and K±→μvμ decay rates has already been performed, using data collected at an early stage of the experiment. The result agrees with the Standard Model expectations. A description of the RK measurement, the physics prospects and the status of the NA62 experiment will be presented in this paper.
