【Abstract】 An MC study of the WW production cross section in pp collisions at a center of mass energy of 10 TeV was presented. The WW→lνl’ν(l,l’=e,μ) decay channels were analyzed using the fully simulated ATLAS Monte Carlo datasets. The expected sensitivity of the measurement was evaluated for an integrated luminosity of 0.2 fb-1. Across the three final states (ee,eμ,μμ),51 signal events and 22 background events are expected. The WW production cross section was expected to be measured at a precision of 17% at the initial phase of the ATLAS experiment.更多还原
