Breakdown of Conventional Factorization for Isolated Photon Cross Sections

Abstract

Using e+eβˆ’β†’Ξ³+Xe^+e^-\rightarrow\gamma + X as an example, we show that the conventional factorization theorem in perturbative quantum chromodynamics breaks down for isolated photon cross sections in a well defined part of phase space. Implications and physical consequences are discussed.Comment: 11 pages, RevTex, 1 figure in postscrip
