The NA62 experiment at CERN collected the world's largest dataset of charged kaon decays in 2016.2018, leading to the first measurement of the branching ratio of the ultra-rare K+ → π+νν¯ decay, based on 20 candidates. Recent results from analyses of K+ → π0e+νγ, K+ → π+μ+μ- and K+ → π+γγ decays, using a data sample recorded in 2017-2018, are reported. Preliminary results of the first observation and analysis of the K± → π0π0μ±ν decay, based on the NA48/2 data collected in 2003-2004, are also shown.

Abstract

The NA62 experiment at CERN collected the world's largest dataset of charged kaon decays in 2016.2018, leading to the first measurement of the branching ratio of the ultra-rare K+ → π+νν¯ decay, based on 20 candidates. Recent results from analyses of K+ → π0e+νγ, K+ → π+μ+μ- and K+ → π+γγ decays, using a data sample recorded in 2017-2018, are reported. Preliminary results of the first observation and analysis of the K± → π0π0μ±ν decay, based on the NA48/2 data collected in 2003-2004, are also shown.
