Abstract

The B⁰, B_s ⁰, B⁺ and Λ_b ⁰ hadron production asymmetries are measured using a data sample corresponding to an integrated luminosity of 3.0 fb⁻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.
