Abstract
The production cross sections of the inclusive Drell-Yan processes $π^Β±βββ’π$ and $π/πΎ^*βββ’β (β=π, π)$ are measured in proton-proton collisions at $\sqrt{s}=7ββTeV$ with the ATLAS detector. The cross sections are reported integrated over a fiducial kinematic range, extrapolated to the full range, and also evaluated differentially as a function of the $π$ decay lepton pseudorapidity and the $π$ boson rapidity, respectively. Based on an integrated luminosity of about $35ββpb^{β1}$ collected in 2010, the precision of these measurements reaches a few percent. The integrated and the differential $π^Β±$ and $π/πΎ^*$ cross sections in the π and π channels are combined, and compared with perturbative QCD calculations, based on a number of different parton distribution sets available at next-to-next-to-leading order.
