Search for the lepton-flavour violating decays B0 → K∗0τ ±µ ∓
A first search for the lepton-flavour violating decays B0 → K∗0τ±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...

| Summary: | A first search for the lepton-flavour violating decays B0 → K∗0τ±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 fb−1. No significant signal is observed, and upper limits on the branching fractions are determined to be B(B0 → K∗0τ+µ−) < 1.0 (1.2) × 10−5 and B(B0 → K∗0τ−µ+) < 8.2 (9.8) × 10−6 at the 90% (95%) confidence level. |
