Initial state gluon radiation studies in Drell-Yan events at the LHC

In the measurement of properties of the top quark and other heavy particles that are produced in proton-proton collisions at the LHC, it is important to account for the effect of initial state gluon radiation (ISR). In order to study ISR at the LHC, we will use a method that has been pioneered by CDF using Drell-Yan events to understand the effect of ISR in top-pair production at the Tevatron. The Drell-Yan process is well suited for ISR studies as it does not suffer from additional final state radiation contributions. We lay out a method in which we determine systematic uncertainties due to ISR by comparing Monte Carlo simulated events to initial data from the ATLAS experiment expected to be taken later this year.
