A Global Fitting Method for Extracting Electroweak Cross Sections in CDF Dilepton Data

We present an analysis of the high-$p_T$ dilepton sample in which we simultaneously extract the $t\bar{t}$, $WW$, and $Z \rightarrow \tau\tau$ cross-sections, with improved precision over more conventional analyses. After selecting events with two high-$p_T$ leptons, we find a 2-D kinematical phase space in which these signals are well separated. We perform a likelihood fit of the data in this phase space to the known contributions in order to extract cross sections of the three predominant processes in the high-$p_T$ dilepton data.
