Description
Using data from the LHCb experiment at CERN, a search for the lepton-flavour-violating decay $B^{+} \to K^{+} \tau^{\pm} \mu^{\mp}$ is being performed. This decay is forbidden in the standard model (SM) of particle physics because it violates the lepton-flavour conservation. However, it is known that the SM cannot account for dark matter, dark energy, the strong $CP$ problem, the neutrino masses, etc. In particular, this decay is interesting since there is emerging evidence for lepton-flavour non-universality, which can be linked to lepton-flavour violation via the introduction of leptoquarks.
In this talk, I will discuss selected aspects of an analysis designed to search for $B^{+} \to K^{+} \tau^{\pm} \mu^{\mp}$ decays using three-prong $\tau$ decays.
