ABSTRACT
The decays [Formula see text] and [Formula see text] are observed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb[Formula see text], collected by the LHCb experiment in proton-proton collisions at the centre-of-mass energies of 7 and 8[Formula see text]. The branching fractions relative to that of [Formula see text] are measured to be [Formula see text]where the first uncertainties are statistical and the second are systematic.
