Nuclear enhanced power corrections to DIS structure functions
Xiaofeng Guo, Jianwei Qiu, Wei Zhu
We calculate nuclear enhanced power corrections to structure functions measured in deeply inelastic lepton-nucleus scattering in Quantum Chromodynamics (QCD). We find that the nucl…
Multiple Parton Scattering in Nuclei: Parton Energy Loss
Xin-Nian Wang, Xiaofeng Guo
Multiple parton scattering and induced parton energy loss is studied in deeply inelastic scattering (DIS) off nuclei. The effect of multiple scattering of a highly off-shell quark…
Nuclear dependence coefficient for the Drell-Yan and J/ production
Xiaofeng Guo, Jianwei Qiu, Xiaofei Zhang
Define the nuclear dependence coefficient in terms of ratio of transverse momentum spectrum in hadron-nucleus and in hadron-nucleon collisions: $\frac{dσ^{hA}}{dq_T^2}/…
Dependence of Drell-Yan Transverse Moemtum Broadening
Xiaofeng Guo, Xiaofei Zhang, Wei Zhu
We analyze dependence of Drell-Yan transverse momentum broadening in hadron-nucleus collisions. In terms of generalized factorization theorem, we show that the dependen…
Gluon mini-jet production in nuclear collisions at high energies
Xiaofeng Guo
We show explicitly that the leading soft gluon distribution, predicted by Kovner, McLerran, and Weigert after solving classical Yang-Mills equations, can be understood in ter…
Probing Quark-Gluon Correlation Functions
Xiaofeng Guo, Jianwei Qiu
We review applicability of QCD factorization theorem to multiple scattering in deeply inelastic lepton-nucleus scattering. We show why A^{1/3}-type nuclear enhancement can be calcu…
