Description

The decay 𝐾+ β†’ πœ‹+πœˆπœˆΜ…, with a very precisely predicted branching ratio of less than 10βˆ’10, is one of the best candidates to reveal indirect effects of new physics at the highest mass scales. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the 𝐾+ β†’ πœ‹+πœˆπœˆΜ… with a decay- in-flight technique, novel for this channel. NA62 took data in 2016, 2017 and another year run is scheduled in 2018. Statistics collected in 2016 allows NA62 to reach the Standard Model sensitivity for 𝐾+ β†’ πœ‹+πœˆπœˆΜ…, entering the domain of 10βˆ’10 single event sensitivity and showing the proof of principle of the experiment. The preliminary result on 𝐾+ β†’ πœ‹+πœˆπœˆΜ… from the analysis of the 2016 data set is presented and prospects for future reviewed.
