Abstract
A search for the baryon- and lepton-number violating decays and is performed at the LHCb experiment using data collected in proton-proton collisions at , 8 and 13 TeV, corresponding to integrated luminosities of 1, 2, and , respectively. No significant signal for and decays is found and the upper limits on the branching fractions are determined to be and , respectively, at 90% (95%) confidence level. These are the first limits on these decays to date.
