Leading soft gluon production in high energy nuclear collisions
Xiaofeng Guo
The leading soft gluon p_T distribution in heavy ion collisions was obtained by Kovner, McLerran, and Weigert after solving classical Yang-Mills equations. I show explicitly this r…
The Leading Power Corrections to the Structure Functions
Xiaofeng Guo, Jianwei Qiu
We show that when Bjorken is large, the leading order twist-four contributions to the structure functions can be expressed in terms of the derivatives of the normal twist-two…
Transverse momentum broadening due to the multiple scattering
Xiaofeng Guo
Using the Drell-Yan process in hadron-nucleus collisions and deeply inelastic lepton-nucleus scattering (DIS) as examples, I show that the transverse momentum broadening can be exp…
Isolated Prompt Photon Production
Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu
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^+e^- \to γ…
Isolated Prompt Photon Cross Sections
Edmond L. Berger, Xiaofeng Guo, Jianwei Qiu
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^+e^-\toγ+…
