dc.description.abstract | The production of B ± mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B ± → J/ ψ K ± decays and data samples corresponding to 1.0 fb-1 and 0.3 fb-1, respectively. The production cross-sections summed over both charges and integrated over the transverse momentum range 0 < p T < 40 GeV/ c and the rapidity range 2.0 < y < 4.5 are measured to be σ ( pp\to {B}^{± }X,√{s}=7 TeV)=43.0± 0.2± 2.5± 1.7 μ b, σ ( pp\to {B}^{± }X,√{s}=13 TeV)=86.6± 0.5± 5.4± 3.4 μ b, where the first uncertainties are statistical, the second are systematic, and the third are due to the limited knowledge of the B ± → J/ ψ K ± branching fraction. The ratio of the cross-section at 13 TeV to that at 7 TeV is determined to be 2.02 ± 0.02 (stat) ± 0.12 (syst). Differential cross-sections are also reported as functions of p T and y. All results are in agreement with theoretical calculations based on the state-of-art fixed next-to-leading order quantum chromodynamics | - |
