LHCb Collaboration; Bernet, R; Müller, K; Serra, N; Steinkamp, O; Straumann, U; Vollhardt, A; et al (2017). Measurement of $B^0, B^0_s, B^+$ and $\Lambda^0_b$ production asymmetries in 7 and 8 TeV proton-proton collisions. Physics Letters B, B774:139-158.

## Abstract

The $B^0, B^0_s, B^+$ and $\Lambda^0_b$ 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 8TeV. The measurements are performed as a function of transverse momentum and rapidity of the bhadrons within the LHCb detector acceptance. The overall production asymmetries, integrated over transverse momentum and rapidity, are also determined.
