Abstract
The CP asymmetry and branching fraction of the Cabibbo-Kobayashi-Maskawa-suppressed decay B+->J/Psipi+ are precisely measured relative to the favored decay B+->J/PsiK+ using a sample of proton-proton collision data corresponding to an integrated luminosity of 5.4 fb-1 recorded at a center-of-mass energy of 13 TeV during 2016-2018.
