| dc.description.abstract | A study of the B +? J / ? ? ¯ p decay using proton-proton collision data collected at s = 8 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6 fb?1, is presented. The ratio of branching fractions B(B+?J/??¯p)/B(B+?J/?K?(892)+) is measured to be (1.054 ± 0.057(stat) ± 0.035(syst) ± 0.011(B))%, where the last uncertainty reflects the uncertainties in the world-average branching fractions of ? ¯ and K*(892) + decays to reconstructed final states. The invariant mass distributions of the J / ? ? ¯ , J/?p, and ? ¯ p systems produced in the B +? J / ? ?¯ p decay are investigated and found to be inconsistent with the pure phase space hypothesis. The analysis is extended by using a model-independent angular amplitude analysis, which shows that the observed invariant mass distributions are consistent with the contributions from excited kaons decaying to the ? ¯ p system. | en_US |
