Abstract

A search is performed for lepton-number-violating B D ( * ) + μ μ decays, using data collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb 1 . No significant signal is observed, and upper limits are set on the branching fractions, B ( B D + μ μ ) < 4.6 × 10 8 and B ( B D * + μ μ ) < 5.9 × 10 8 , at the 95% confidence level.
