QCD Factorization of Quasi Generalized Gluon Distributions
J. P. Ma, Z. Y. Pang, C. P. Zhang +1
We study the factorization relations between quasi gluon GPDs and twist-2 GPDs. The perturbative coefficient functions are obtained at one-loop level. They are free from any collin…
QCD Factorization of Quasi Generalized Quark Distributions
J. P. Ma, Z. Y. Pang, G. P. Zhang
We study the factorization of quasi generalized quark distributions with twist-2 generalized parton distributions. We use an approach which is different than that used in literatur…
Twist-3 Double Spin Asymmetries in Drell-Yan Processes
M. C. Hu, J. P. Ma, Z. Y. Pang +1
We study double spin asymmetries in Drell-Yan processes in which one initial hadron is transversely polarized and another one is longitudinally polarized. The complete part of the…
Parton Interpretation and Twist-4 Parton Distributions
J. P. Ma, Z. Y. Pang, G. P. Zhang
Through explicit examples we show that twist-4 parton distributions have no parton interpretation in the sense that parton or partons inside a hadron can carry the momentum fractio…
