Abstract
The branching fraction of the decay is measured using collision data corresponding to an integrated luminosity of , collected using the LHCb detector at a center-of-mass energy of 7 TeV. It is found to be , where the uncertainties are statistical, systematic, and due to the normalization channel, respectively. The branching fractions of the individual decays corresponding to the presence of one or two are also measured. The individual branching fractions are found to be , . All three results are the most precise determinations to date.
