Abstract
A study of Bc+->chi_cpi+ decays is reported using proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb-1. The decay Bc+->chi_{c2}pi+ is observed for the first time, with a significance exceeding seven standard deviations. The relative branching fraction with respect to the Bc+->J/Psipi+ decay is measured to be (Formula presented.) See .pdf version.File in questo prodotto:
