Isolated Prompt Photon Cross Sections

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We show that the conventionally defined partonic cross section for the production of isolated prompt photons is not an infrared safe quantity. We work out the case of e+eγ+Xe^+e^-\to\gamma + X, and discuss implications for hadron reactions.
