(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) Abstract The ratio of branching fractions and the difference in CP asymmetries of the decays B + [arrow right] J/ + and B + [arrow right] J/[psi]K + are measured using a data sample of pp collisions collected by the LHCb experiment, corresponding to an integrated luminosity of 3 fb-1 at centre-of-mass energies of 7 and 8 TeV. The results are ... ... where the first uncertainties are statistical and the second are systematic. Combining this result with a recent LHCb measurement of ... provides the most precise estimate to date of CP violation in the decay B + [arrow right] J/ψπ +, ...[Figure not available: see fulltext.]
