Query: $K^+\rightarrow \pi^+\nu\bar\nu$ decay and NP searches at NA62   $K\rightarrow \pi\nu \bar\nu$ is one of the theoretically cleanest meson
decay where to look for indirect effects of new physics complementary to LHC
searches. The NA62 experiment at CERN SPS is designed to measure the branching
ratio of the $K^+\rightarrow \pi^+\nu \bar\nu$ decay with 10\% precision. After
commissioning, in 2016 first data set good for physics has been collected. The
data taking is foreseen till the LS2 at the end of 2018. The analysis method
has been tested with 5\% of the full 2016 statistics. Results obtained with
this subsample will be shown. The status of the experiment will be reviewed,
and prospects will be presented, together with a mention to the broader NA62
physics program.
