Abstract

The high precision of the theoretical prediction and the strong suppression make the ultra-rare kaon decay K+ → π+νν¯ an excellent probe for new physics. The NA62 experiment at CERN SPS aims to measure BR(K+ → π+νν¯) with a 10% precision. NA62 collected data in 2016, 2017 and 2018. The 2016 data has been analyzed and the result published: one candidate signal event was found, showing that the decay-in-flight techinque works. The 2017 sample is currently under analysis and 2.5 ± 0.4 Standard Model signal events are expected, while the background is still under study.
