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. These results improve by 1 order of magnitude over previous results for these decay modes.

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. These results improve by 1 order of magnitude over previous results for these decay modes.File in questo prodotto:
