Abstract A first search for the lepton-flavour violating decays B0K0τ±μ 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 13 TeV between 2011 and 2018, corresponding to an integrated luminosity of 9 fb1. No significant signal is observed, and upper limits on the branching fractions are determined to be B(B0K0τ+μ)<1.0 (1.2)×105 and B(B0K0τμ+)<8.2 (9.8)×106 at the 90% (95%) confidence level.
