Abstract
We study the effects of threshold resummation on the rapidity dependence of single-particle-inclusive cross sections, using the prompt photon cross se ction as an example. We make use of the full resummation formula at next-to -leading logarithmic accuracy and develop a new technique for treating rapi dity in resummation. We compare our phenomenological results with those of previous studies and discuss the close relation between resummation formali sms in the literature.
