Abstract
The total cross section and differential cross sections for the production of B ± c mesons, times their branching fraction to J / ψ π ± , are measured relative to those for the production of B ± mesons, times their branching fraction to J / ψ K ± . The data used for this study correspond to an integrated luminosity of 20.3 fb − 1 of p p collisions recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a center-of-mass energy of √ s = 8 TeV . The measurement is performed differentially in bins of transverse momentum p T for 13 GeV < p T ( B ± c ) < 22 GeV and p T ( B ± c ) > 22 GeV and in bins of rapidity y for | y | < 0.75 and 0.75 < | y | < 2.3 . The relative cross section times branching fraction for the full range p T > 13 GeV and | y | < 2.3 is ( 0.34 ± 0.0 4 stat + 0.06 − 0.02 sys ± 0.0 1 lifetime ) % . The differential measurements suggest that the production cross section of the B ± c decreases faster with p T than the production cross section of the B ± , while no significant dependence on rapidity is observed.
