W and Z Production in pp Collisions at 7TeV with ATLAS
Measurements of W and Z cross-sections in pp collisions at ECM = 7 TeV at the Large Hadron Collider are reported from the ATLAS experiment. From an observation of 118 leptonic W candidates, the inclusive W cross-section times leptonic branching fraction is measured as [9.3 \pm 0.9(stat) \pm 0.6(syst...

| Sumario: | Measurements of W and Z cross-sections in pp collisions at ECM = 7 TeV at the Large Hadron Collider are reported from the ATLAS experiment. From an observation of 118 leptonic W candidates, the inclusive W cross-section times leptonic branching fraction is measured as [9.3 \pm 0.9(stat) \pm 0.6(syst) \pm 1.0(lumi)] nb. The result for the Z boson is [0.83 \pm 0.07(stat) \pm 0.06(syst) \pm 0.09(lumi)] nb. These results agree with theoretical expectations from NNLO QCD. |
