Description

The K+ to pi+ nu nubar decay has been attracting interests for many decades. The accurate measurement its branching ratio is a powerful test of the Standard Model (SM) and could reveal beyond the SM effects.

As the decay occurs at the level of 1 in 10 billion kaon disintegration, many experimental challenges have to be overcome.

The CERN NA62 experiment uses a novel kaon decay-in-flight technique to observe K+ to pi+ nu nubar. The 2016 data set established the method by allowing us to reach the 10^-10 single event sensitivity.

The preliminary NA62 result on K+ to pi+ nu nubar from the analysis of the full 2016 data set will be presented.
