Summary:Title screen
The branching fraction and direct CPCP asymmetry of the decay B+→J/ψρ+B+→J/ψρ+ 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 fb −1 fb −1. The following results are obtained:B(B+→J/ψρ+)ACP(B+→J/ψρ+)=(3.81+0.25−0.24±0.35)×10−5,=−0.045+0.056−0.057±0.008,B(B+→J/ψρ+)=(3.81−0.24+0.25±0.35)×10−5,ACP(B+→J/ψρ+)=−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.
