Measurement of the B± production cross-section in pp collisions at s = 7 $$ \sqrt{s}=7 $$ and 13 TeV

The production of B mesons is studied in pp collisions at centre-of-mass energies of 7 and 13 TeV, using B J/ 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
