In this talk I will review the recent progress and results concerning next-to-leading power factorization. I will mostly focus on semi-inclusive DIS process, showing the derivation of the structure functions at one-loop accuracy.
I will comment on some of the specific details that emerge at next-to-leading power, such as the cancellation of special rapidity divergences and the emergence of...
In view of the increasing precision of theoretical calculations and experimental measurements, power corrections to transverse-momentum-dependent observables have become highly important. Power corrections for TMD observables are a rich and complex subject, and are difficult to grasp even in the most simple scenarios. Our goal is to understand TMD factorization at next-to-leading power for a...
In this talk, I will show a general expression for weighted cross sections in leptonic annihilation to hadrons based on time-ordered perturbation theory (TOPT). For any infrared-safe weight, the cancellation of infrared divergences is implemented locally at the integrand level, and in principle can be evaluated numerically in four dimensions. We go on to show that it is possible to eliminate...
