We study corrections suppressed by one power of the soft gluon energy to the resummation of threshold logarithms for the Drell-Yan cross section. We find that these corrections can be divided in a set of factorizable and a set of non-factorizable contributions. We prove exponentiation for the former, and develop a framework for systematic treatment of the non-factorizable corrections.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
