Prospects for $K^+\rightarrow \pi^+ \nu \bar\nu$ observation at CERN in NA62

Abstract

The rare decay K + → π + νν is an excellent process to probe Standard Model and indirectly search for new physics, complementary to the ongoing direct LHC searches. The NA62 experiment at CERN SPS aims to collect about 100 of such events in two years of data taking, keeping the background at the level of 10%. The physics motivation, experimental technique and status of the experiment are presented.
