Scientific paper

We present a method for the simultaneous extraction of Standard Model (SM) processes using the eμ dilepton final state. In a 2-D phase space defined by missing transverse energy and jet multiplicity the main SM contributions of tt, WW, and Z ->ττ are well separated. After selecting eμ events, and making no further requirements on the events, we fit the data to templates of the three aforementioned processes, the normalizations of which are allowed to float, and smaller contributions which are constrained to their uncertainties. The result of the likelihood fit provides the simultaneous measurement of the tt, WW, and Z ->ττ cross-sections, as well as providing a more global test of the SM as compared to a more conventional cross-section measurement. We present results from 5 fb-1 of data collected by the ATLAS detector.
