The production cross-sections summed over both charges and integrated over the transverse momentum range 0 < pT < 40 GeV/c and the rapidity range 2.0 < y < 4.5 are measured to be sigma-(pp -> B-+/- X, root s = 7 TeV) = 43.0 +/- 0.2 +/- 2.5 +/- 1.7 $\mu$b, sigma(pp -> B-+/- X, root s = 13 TeV) = 86.6 +/- 0.5 +/- 5.4 +/- 3.4 $\mu$b, where the first uncertainties are statistical, the second are systematic, and the third are due to the limited knowledge of the B-+/- -> J/psi 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 pi, and y. All results are in agreement with theoretical calculations based on the state-of-art fixed next-to-leading order quantum chromodynamics.", optnote="WOS:000417757900004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3427), last updated on Thu, 04 Jan 2018 14:12:31 +0000", issn="1029-8479", doi="10.1007/JHEP12(2017)026", opturl="http://arxiv.org/abs/1710.04921", opturl="https://doi.org/10.1007/JHEP12(2017)026", archivePrefix="arXiv", eprint="1710.04921", language="English" }
