【2.7】 High-Energy Limit of QCD beyond Sudakov Approximation
Seminar
Title: High-Energy Limit of QCD beyond Sudakov Approximation
Speaker: Dr.Tao Liu (劉濤) (University of Alberta)
Time: 9:00AM, Feb.7th, 2018
Place: Theoretical Physics Division, 319
Abstract: Evaluating the scattering amplitudes in the high-energy limit is a fundamental problem of quantum field theory. The resummation of Sudakov-type corrections is well established at leading power. Here we explore the structure of mass-suppressed double-logarithmic corrections which are induced by soft quark exchange. Physical applications, e.g., the bottom-quark contribution to hadronic Higgs production will also be discussed.
