Search for the lepton-flavor violating decay Bs0 →φμ±τ

Aaij, R. ; Ruiz-Vidal, Joan LU and Zunica, G. (2024) In Physical Review D 110(7).
Abstract
A search for the lepton-flavor violating decays Bs0→φμ±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(Bs0→φμ±τ)
