The NA62 experiment at CERN SpS collected a large sample of charged kaon decays with a low intensity beam and minimum bias trigger conditions in 2007. This allowed measurements of a number of rare decays that are difficult to address in conventional high intensity experiments with highly selective trigger conditions. In particular, large samples of K > pi gamma gamma and K > e nu gamma decays have been collected, allowing precision tests of the Chiral Perturbation Theory. The status and first results of these analyses are presented.

Abstract

The NA62 experiment at CERN SpS collected a large sample of charged kaon decays with a low intensity beam and minimum bias trigger conditions in 2007. This allowed measurements of a number of rare decays that are difficult to address in conventional high intensity experiments with highly selective trigger conditions. In particular, large samples of K > pi gamma gamma and K > e nu gamma decays have been collected, allowing precision tests of the Chiral Perturbation Theory. The status and first results of these analyses are presented.
