      abstract     = {A search is presented for the lepton flavour violating
                      decay B$^{+}$ → K$^{+}$μ$^{−}$τ$^{+}$ using a sample
                      of proton-proton collisions at centre-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 inclusively,
                      primarily via decays with a single charged particle. The
                      four-momentum of the τ lepton is determined by using
                      B$^{+}$ mesons from $ {B}_{s2}^{\ast 0}\to {B}^{+}{K}^{-} $
                      decays. No significant excess is observed, and an upper
                      limit is set on the branching fractionℬ(B$^{+}$ →
                      K$^{+}$μ$^{−}$τ$^{+}$) < 3.9 × 10$^{−5}$ at 90 \%
                      confidence level.The obtained limit is comparable to the
                      world-best limit.},
