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/psiK+, B0 -> J/psiK*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.

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/psiK+, B0 -> J/psiK*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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
