dc.description.abstract | The production cross-sections of B mesons are measured in pp collisions at a centre-of-mass energy of 7 TeV, using data collected with the LHCb detector corresponding to a integrated luminosity of 0.36 fb−1 . The B+, B0 and B0 s mesons are reconstructed in the exclusive decays B+ → J/ψ K+, B0 → J/ψ K∗0 and B0 s → J/ψ φ, with J/ψ → µ +µ −, K∗0 → K+π − and φ → K+K−. The differential cross-sections are measured as functions of B meson transverse momentum pT and rapidity y, in the range 0 < pT < 40 GeV/c and 2.0 < y < 4.5. The integrated cross-sections in the same pT and y ranges, including charge-conjugate states, are measured to be σ(pp → B+ + X) = 38.9 ± 0.3 (stat.) ± 2.5 (syst.) ± 1.3 (norm.) µb, σ(pp → B0 + X) = 38.1 ± 0.6 (stat.) ± 3.7 (syst.) ± 4.7 (norm.) µb, σ(pp → B0 s + X) = 10.5 ± 0.2 (stat.) ± 0.8 (syst.) ± 1.0 (norm.) µb, where the third uncertainty arises from the pre-existing branching fraction measurements. | - |
