A first search for the lepton-flavour violating decays B-0 -> K{*}0 tau(+/-)mu -/+ is presented.

Abstract

A first search for the lepton-flavour violating decays B-0 -> K{*}0 tau(+/-)mu -/+ is presented. The analysis is performed using a sample of proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13TeV between 2011 and 2018, corresponding to an integrated luminosity of 9 fb(-1). No significant signal is observed, and upper limits on the branching fractions are determined to be B(B-0 -> K{*}0 tau(+)mu(-)) < 1.0 (1.2) x 10(-5) and B(B-0 -> K{*}0 tau(-)mu(+)) < 8.2 (9.8) x 10(-6) at the 90\% (95\%) confidence level.
