Universality at next-to-leading power for jet associated processes

Abstract

The study of cross-sections in the threshold limit at next-to-leading power has been a subject of sustained interest for many years. We demonstrate the universality of leading logarithms at next-to-leading power for the production of arbitrary massive colourless particles in association with a jet, contingent upon the identification of appropriate combination of helicity configurations.
