Double Parton scattering in 2fb$^{-1}$ of CDF II W-$>$e$\upsilon$ + jets data
POSTER
Abstract
Search for Evidence of Double Parton Scattering events in W-$>$e$\upsilon $ + jets in 2fb$^{-1}$ CDF II data is presented. Silicon and COT tracking system is used for vertex reconstruction of the Low energy jets. Multiple Interactions (two different ppbar collisions) distinguished by applying a cut on $\Delta $Z between electron track Z and Jet Z Vertex. To discriminate Signal from the background, Azimuthal angular distributions are fit for single plus multiple parton collision model. Work is in progress to obtain the Double Parton fraction present in data.
