Abstract

The production of B± mesons in proton-proton collisions at √s = 7 TeV is studied using 35 pb^−1 of data collected by the LHCb detector. The B± mesons are reconstructed exclusively in the B± → J/ψ K± mode, with J/ψ → μ+ μ−. The differential production cross-section is measured as a function of the B± transverse momentum in the fiducial region 0 < p_T < 40 GeV/c and with rapidity 2.0 < y < 4.5. The total cross-section, summing up B+ and B−, is measured to be σ(pp → B± X, 0 < p_T < 40 GeV/c, 2.0 < y < 4.5) = 41.4 ± 1.5 (stat.) ± 3.1 (syst.) μb.
