Abstract

The NA62 experiment at CERN SPS was designed to measure the \(BR(K^{+}\rightarrow \pi ^{+}\nu \bar \nu )\) with a decay-in-flight technique. NA62 took data in 2016, 2017 and 2018. Statistics collected in 2016 allowed NA62 to reach the Standard Model sensitivity and to show the proof of principle of the experiment. The preliminary result from the 2016 data set is presented.
