The measurements are performed as a function of transverse momentum and pseudorapidity of the B0 and B0 s mesons within the LHCb acceptance. The production asymmetries, integrated over pT and η in the range 4 < pT < 30 GeV/c and 2.5 < η < 4.5, are determined to be AP(B0 ) = (−0.35 ± 0.76 ± 0.28)% and AP(B0 s ) = (1.09 ± 2.61 ± 0.66)%, where the first uncertainties are statistical and the second systematic.23 p.application/pdfengcc-by (c) Garrido, Lluis et al., 2014https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6457172022-05-16info:eu-repo/semantics/openAccess
