Abstract
The B-0, B-s(0), B+ and lambda(0)(b) hadron production asymmetries are measured using a data sample corresponding to an integrated luminosity of 3.0 fbc(-1), collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. The measurements are performed as a function of transverse momentum and rapidity of the b hadrons within the LHCb detector acceptance. The overall production asymmetries, integrated over transverse momentum and rapidity, are also determined. (c) 2017 The Author(s).
