  The differential cross sections for inclusive production of B+ hadrons are
measured as a function of the B+ transverse momentum pT[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 49.4 inverse
picobarns. The measurement uses the exclusive decay channel B+ to J/psi K+,
with J/psi mesons that decay to a pair of muons. The results show a reasonable
agreement with theoretical calculations within the uncertainties.
