N2 - A search for the lepton-flavor violating decays Bs0?fµ±t 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 t 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 B(Bs0?fµ±t)<1.0×10-5 at 90% confidence level.
