Abstract
The CERN NA62 experiment is dedicated to rare kaon decays. Data collected during Run1 (2016-2017-2018) already constitute the largest sample ever of detected K+ decays and offer unprecedented opportunities to test the SM or to search for New Physics in a variety of rare kaon and pion decays. The preliminary NA62 precision measurement of the π0 → e+e− decay branching fraction is reported in the following, together with the recently published study of the K+ → π+γγ decay and the first search for an axion-like particle (a) coupling to gluons in the decay chain K+ → π+a,a → γγ.
