Simultaneous measurements of $t\bar{t}$, $WW$ and $Z/\gamma^*\to \tau^+\tau^-$ production at $\sqrt{s}=7$ TeV with the ATLAS detector
A global test of these Standard Model predictions is presented through the study of the common final state made up of a pair of an oppositely charged electron and muon in proton-proton collisions at sqrt(s) = 7 TeV recorded by the ATLAS detector at the LHC.

| description | A global test of these Standard Model predictions is presented through the study of the common final state made up of a pair of an oppositely charged electron and muon in proton-proton collisions at sqrt(s) = 7 TeV recorded by the ATLAS detector at the LHC. The simultaneous measurement of the cross-sections of the pair production of top quarks, tau-leptons via Drell-Yan, and WW bosons is performed. The simultaneous extraction of the cross-sections is performed in a two-dimensional phase space spanned by missing transverse momentum and jet multiplicity. This analysis allows for a broader test of the Standard Model than that given by dedicated cross-section measurements providing the underlying correlations in the predicted and measured cross-sections due to common proton parton distribution functions parameters. This measurement can help to improve predictions of interaction cross-sections in hadron collisions. |
