Drell-Yan process in soft-collinear effective theory near end-point
Jong-Phil Lee
Abstract
The Drell-Yan process is analyzed in soft-collinear effective theory near the end-point region. It is assumed that the relevant final-state hadron energy Q(1-z) where z is the momentum fraction transferred to the virtual photon is the typical hadronic scale Λ, thus no intermediate scale exists. It is shown that this setup successfully reproduces the full theory results. We also discuss the factorized soft Wilson lines for the Drell-Yan process.
