Abstract

The B± meson production asymmetry in pp collisions is measured using B+→¯D0π+ decays. The data were recorded by the LHCb experiment during Run 1 of the LHC at center-of-mass energies of √s=7 and 8 TeV. The production asymmetries, integrated over transverse momenta in the range 2<pT<30  GeV/c, and rapidities in the range 2.1<y<4.5 are measured to be Aprod(B+,√s=7  TeV)=(−0.41±0.49±0.10)×10−2, Aprod(B+,√s=8  TeV)=(−0.53±0.31±0.10)×10−2, where the first uncertainties are statistical and the second are systematic. These production asymmetries are used to correct the raw asymmetries of B+→J/ψK+ decays, thus allowing a measurement of the CP asymmetry, ACP(B+→J/ψK+)=(0.09±0.27±0.07)×10−2.
