A search for the lepton-flavor violating decays Bs0->Phi mu^{\pm}tau^{\mp} is presented, using a sample of proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9 fb-1. The tau leptons are selected using decays with three charged pions. No significant excess is observed, and an upper limit on the branching fraction is determined to be BR(Bs0\to Phimu^{\pm}\tau{\mp})<1.0x10-5 at 90% confidence level.

Abstract
A search for the lepton-flavor violating decays Bs0->Phi mu^{\pm}tau^{\mp} is presented, using a sample of proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9 fb-1. The tau leptons are selected using decays with three charged pions. No significant excess is observed, and an upper limit on the branching fraction is determined to be BR(Bs0\to Phimu^{\pm}\tau{\mp})<1.0x10-5 at 90% confidence level.File in questo prodotto:
