Cross section measurements of high-p{sub T} dilepton final-state processes using a global fitting method
We present a new method for studying high-p{sub T} dilepton events (e{sup {+-}}e{sup {+-}}, {mu}{sup {+-}}{mu}{sup {+-}}, e{sup {+-}}{mu}{sup {+-}}) and simultaneously extracting the production cross sections of pp{yields}tt, pp{yields}W{sup +}W{sup -}, and pp{yields}Z{sup 0}{yields}{tau}{sup +}{tau...
