چکیده A search for flavor violating decays of the boson to charged leptons is performed using data from proton-proton collisions at \sqrt{s}=13TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 138 fb^-1. Each of the decays is considered. The data are consistent with the backgrounds expected from standard model processes. For the channel the observed (expected) 95% confidence level upper limit on the branching fraction is 1.9(2.0)×10-7, which is the most stringent direct limit to date on this process; the corresponding limits for the channels are 13.8(11.4)×10^-6 and 12.0(5.3)×10^-6, respectively. Additionally, the final state is used to search for lepton flavor violating decays of resonances in the mass range from 110 to 500GeV. No significant excess is observed above the predicted background levels.
