High Energy Physics Seminar

Although the high-energy limit of gauge theory amplitudes in an old and well-studied subject, comparatively little is known about gravity.  Many basic questions remain about graviton Reggeization and graviton Regge physics more broadly.  More confusingly, the high-energy limit in gravity is known to coincide with the classical limit.  In this talk, I will address these questions using an effective field theory for high energy scattering in gravity.  In particular, I clarify the role of Regge physics in gravity and more generally address the question of resummability of large logs.  Lastly, I explain the interplay between classical and Regge physics, and how one may use this to calculate large logs appearing in classical observables to high loop order.

The talk is in 469 Lauritsen.
