Abstract

The measurements of the ¯B0-B0 and ¯B0s - B0s production asymmetries, AP(B0) and AP(B0s) performed by LHCb, using pp collisions data at the centre-of-mass energy of 7TeV, corresponding to an integrated luminosity of 1 fb−1, are reported. Integrating over pT and η, in the ranges 4 < pT < 30 GeV/c and 2.5 < η < 4.5, the production asymmetries are found to be AP(B0) = −0.35 ± 0.76 (stat) ± 0.28 (syst)% and AP(B0s) = 1.09 ± 2.61 (stat) ± 0.61 (syst)%.
