Abstract
search is performed for lepton-number-violating B− → DðÞþμ−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, BðB− → Dþμ−μ−Þ < 4.6 × 10−8 and BðB− → Dþμ−μ−Þ < 5.9 × 10−8, at the 95% confidence level.| File | Dimensione | Formato | |
