Resumen

The B0-B0 and Bs 0Bs 0 production asymmetries, AP(B0) and AP(Bs 0), are measured by means of a time-dependent analysis of B0→J/ψK*0, B0→D-π+ and Bs 0→Ds-π+ decays, using a data sample corresponding to an integrated luminosity of 1.0fb-1, collected by LHCb in pp collisions at a centre-of-mass energy of 7TeV. The measurements are performed as a function of transverse momentum and pseudorapidity of the B0 and Bs 0 mesons within the LHCb acceptance. The production asymmetries, integrated over pT and η in the range 4<pT<30GeV/c and 2.5<η<4.5, are determined to be AP(B0)=(-0.35±0.76±0.28)% and AP(Bs 0)=(1.09±2.61±0.66)%, where the first uncertainties are statistical and the second systematic.
