Universality in nuclear dependence coefficient $α (q_{T})$

Xiaofeng Guo, Jianwei Qiu, Xiaofei Zhang

We derive the nuclear dependence coefficient $α (q_{T})$ for Drell-Yan and J/ $ψ$ production. We show that at small $q_{T}$ , the $α (q_{T})$ is given by an universal functional form: $α(q_T…

Isolated Prompt Photon Production in Hadronic Final States of $e^{+} e^{-}$ Annihilation

Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu

We provide complete analytic expressions for the isolated prompt photon production cross section in $e^{+} e^{-}$ annihilation reactions through one-loop order in quantum chromodynamics…

Breakdown of Conventional Factorization for Isolated Photon Cross Sections

Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu

Using $e^{+} e^{-} \to γ + X$ as an example, we show that the conventional factorization theorem in perturbative quantum chromodynamics breaks down for isolated photon cross sectio…

Nuclear Dependence in Direct Photon Production

Xiaofeng Guo, Jianwei Qiu

We calculate the nuclear dependence of direct photon production in hadron-nucleus collisions. In terms of a multiple scattering picture, we factorize the cross section for direct p…
