Abstract

Searches for the lepton number violating decay and the lepton flavor violating and decays are reported using data collected by the NA62 experiment at CERN in 2017-2018. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% confidence level: , and . These results improve by 1 order of magnitude over previous results for these decay modes.
