The branching fraction of the decay , relative to the topologically similar decay , is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of . The ratio is found to be , where the first uncertainty is statistical and the second systematic. Using the world-average branching fraction for , the branching fraction for the decay is found to be , where the first uncertainty is statistical, the second systematic, and the third is due to the branching fraction of the normalization channel.
