dc.description.abstractThe total cross section and differential cross sections for the production of B c mesons, times their branching fraction to J=ψπ , are measured relative to those for the production of B mesons, times their branching fraction to J=ψK . The data used for this study correspond to an integrated luminosity of 20.3 fb−1 of pp collisions recorded by the ATLAS detector at the Large Hadron Collider in 2012 at a center-of-mass energy of ffiffiffi s p ¼ 8 TeV. The measurement is performed differentially in bins of transverse momentum pT for 13 GeV < pTðB c Þ < 22 GeV and pTðB c Þ > 22 GeV and in bins of rapidity y for jyj < 0.75 and 0.75 < jyj < 2.3. The relative cross section times branching fraction for the full range pT > 13 GeV and jyj < 2.3 is ð0.34 0.04stat þ0.06 −0.02 sys 0.01lifetimeÞ%. The differential measurements suggest that the production cross section of the B c decreases faster with pT than the production cross section of the B , while no significant dependence on rapidity is observed.es_ES
