Measurement of the differential inclusive B⁺ Hadron Cross Sections in pp Collisions at √s = 13 TeV

Abstract

The differential cross sections for inclusive production of \({B}^{+}\) hadrons are measured as a function of the \({B}^{+}\) transverse momentum \({{p}_{T}}^{B}\) and rapidity \({y}^{B}\) in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 48.1 pb\({-1}\). The measurement uses the exclusive decay channel \({B}^{+}\to \text{J}/\psi {K}^{+}\), with \(\text{J}/\psi \) mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties.
