Description

We present the studies of initial state radiations (ISR) in Drell-Yan events from ppbar collisions at sqrt{s}=1.96TeV with CDF Run II data. ISR from hadron collisions plays an important role in jet physics, which has an impact on precision measurements and searches for new physics. We develop a systematic way to study the ISR effect using Drell-Yan events. The truncated mean of the dilepton transverse momentum distribution is found to have a logarithmic slope as a function of dilepton invariant mass square. This logarithmic slope can be used to control ISR effect in the SM processes and new physics processes.
