Abstract: The decay K+→π+ν ̄ν, with a very precisely predicted branching ratio of less than 10−10, 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 Br(K+→π+ν ̄ν) with a decay-in-flight technique, novel for this channel. NA62 took data in 2016, 2017 and 2018. Statistics collected in2016 and 2017 allows NA62 to reach the Standard Model sensitivity for K+→π+ν ̄ν; the analysis of the 2018 data leads to the most precise measurement ever performed. The preliminary result of Br(K+→π+ν ̄ν) measurement from the analysis of the full data set 2016-2017-2018 is presented, and other recent results will be reviewed. Prospects for future NA62 data-taking, beginning in 2021, are also discussed.
