Using a data sample corresponding to an integrated luminosity of 3.0 fb -1, collected by LHCb in pp collisions at centre-of-mass energies of 7 and 8TeV, the B+, B0, B0 s and L0b production asymmetries are measured using B+ ->’ J/psiˆK+, B0 ->’ J/psiˆK*ˆ—0 and B0s ->’ Ds- pi†+ decays.

Abstract

Using a data sample corresponding to an integrated luminosity of 3.0 fb -1, collected by LHCb in pp collisions at centre-of-mass energies of 7 and 8TeV, the B+, B0, B0 s and L0b production asymmetries are measured using B+ ->’ J/psiˆK+, B0 ->’ J/psiˆK*ˆ—0 and B0s ->’ Ds- pi†+ decays. The measurements are performed as a function of the transverse momentum (pT ) and rapidity (y) of the b hadrons and then finally integrated in the ranges 2 < pT < 30 GeV/c and 2.1 < y < 4.5. No evidence of production asymmetry is found within the current experimental uncertainties.
