Abstract

A search for the baryon- and lepton-number violating decays B0 → p μ− and B0s → p μ− is performed at the LHCb experiment using data collected in proton-proton collisions at √s = 7, 8 and 13 TeV, corresponding to integrated luminosities of 1, 2, and 6 fb^−1, respectively. No significant signal for B0 → p μ− and B0s → p μ− decays is found and the upper limits on the branching fractions are determined to be B(B0 → p μ−) < 2.6 (3.1) × 10^−9 and B(B0s → p μ−) < 12.1 (14.0) × 10^−9, respectively, at 90% (95%) confidence level. These are the first limits on these decays to date.
