First Results from ATLAS on Production of W and Z Bosons in proton-proton Collisions at sqrt(s)=7 TeV

The ATLAS results from W/Z boson cross section measurements with ~320nb^-1 are presented. An overview of the analysis procedure is shown, including signal sample selection, background estimation and cross-section calculation. Additionally, the ratio of W/Z cross-sections is presented together with a...

Sumario:The ATLAS results from W/Z boson cross section measurements with ~320nb^-1 are presented. An overview of the analysis procedure is shown, including signal sample selection, background estimation and cross-section calculation. Additionally, the ratio of W/Z cross-sections is presented together with a measurement of W charge asymmetry. As an outlook, most recent plots with ~35pb^-1 are shown.
