First observations of the , and decays are made using a dataset corresponding to an integrated luminosity of collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of . The ratios of the branching fractions of each of the modes with respect to the corresponding decays are where the third uncertainty corresponds to the uncertainties of the dilepton branching fractions of the and meson decays. |
