Description

The production cross sections of the inclusive Drell-Yan processes $π‘Š^Β±β†’β„“β’πœˆ$ and $𝑍/𝛾^*→ℓ⁒ℓ (β„“=𝑒, πœ‡)$ are measured in proton-proton collisions at $\sqrt{s}=7  TeV$ 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 $π‘Š$ decay lepton pseudorapidity and the $𝑍$ boson rapidity, respectively. Based on an integrated luminosity of about $35  pb^{βˆ’1}$ collected in 2010, the precision of these measurements reaches a few percent. The integrated and the differential $π‘Š^Β±$ and $𝑍/𝛾^*$ cross sections in the 𝑒 and πœ‡ 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.
