Gluon Thrust: Endpoint Factorization and Next-to-leading Power Resummation
by
Advancing the precision of theoretical predictions is a key ingredient in the ongoing Standard Model tests and searches for physics beyond our current paradigm. Soft Collinear Effective Theory (SCET) has been successfully applied to improve the precision of many important observables in collider physics. It is now standard practice to use SCET to derive factorization theorems and apply renormalization group (RG) methods to perform the leading power resummation of large logarithmic contributions that appear in regions of phase space with disparate energy scales. In this talk, I will present the recent developments in taking the step beyond the leading term in the power expansion. Focusing on the example of off-diagonal "gluon" thrust, I will discuss how the factorization formula free of endpoint divergences in four dimensions can be obtained, and how this factorization formula allows us to resum next-to-leading power logarithms using RGE methods.
