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.
