Measurement of the branching fraction and [Formula omitted] asymmetry in [Formula omitted] decays

Measurement of the branching fraction and [Formula omitted] asymmetry in [Formula omitted] decays

The branching fraction and direct [Formula omitted] asymmetry of the decay [Formula omitted] are measured using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7 and 8 TeV, corresponding to a total integrated luminosity of 3 [Formula omitted]. The followin...

Zusammenfassung:The branching fraction and direct [Formula omitted] asymmetry of the decay [Formula omitted] are measured using proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7 and 8 TeV, corresponding to a total integrated luminosity of 3 [Formula omitted]. The following results are obtained: B(B+[right arrow]J/[psi][rho]+)=(3.81-0.24+0.25±0.35)x10-5,ACP(B+[right arrow]J/[psi][rho]+)=-0.045-0.057+0.056±0.008,where the first uncertainties are statistical and the second systematic. Both measurements are the most precise to date.
