Search for Lepton Number and Flavor Violation in and Decays Article uri icon

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%25 confidence level: , and . These results improve by 1 order of magnitude over previous results for these decay modes. © 2021 Published by the American Physical Society
