【 摘 要 】

The K+→π+νν branching ratio is one of the key observables to test the Standard Model. The NA62 experiment has been designed to measure this branching ratio with a 10% precision. Most of the experiment systems have been commissioned during 2014 and 2015 runs and physics data have been recorded. The analysis of this data shows performances close to the nominal ones.
