Abstract

A search for the lepton-flavor violating decays B0s → ϕ μ± τ∓ 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 τ 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(B0s → ϕ μ± τ∓) < 1.0 × 10^−5 at 90% confidence level.
