Threshold Resummation and Rapidity Dependence

arXiv:hep-ph/0011289 · doi:10.1088/1126-6708/2001/02/016

Abstract

We study the effects of threshold resummation on the rapidity dependence of single-particle-inclusive cross sections, using the prompt photon cross section as an example. We make use of the full resummation formula at next-to-leading logarithmic accuracy and develop a new technique for treating rapidity in resummation. We compare our phenomenological results with those of previous studies and discuss differences and similarities of the two existing resummation formalisms.
