T-odd Effect from Two-Photon Exchange in SIDIS at Low Transverse Momentum
J. P. Ma, G. P. Zhang
We study T-odd effects through two-photon exchange in semi-inclusive deeply inelastic scattering in the kinematic region where the produced hadron has a low transverse momentum. Th…
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…
One-Loop Corrections of Single Spin Asymmetries in Semi-Inclusive DIS
A. P. Chen, J. P. Ma, G. P. Zhang
We study single spin asymmetries at one-loop accuracy in semi-inclusive DIS with a transversely polarized hadron in the initial state. Two measurable spin observables are predicted…
One-Loop Corrections of Single Spin Asymmetries at Twist-3 in Drell-Yan Processes
A. P. Chen, J. P. Ma, G. P. Zhang
We study single spin asymmetries at one-loop accuracy in Drell-Yan processes in which one of the initial hadrons is transversely polarized. The spin-dependent part of differential…
Gauge Invariance and QCD Twist-3 Factorization for Single Spin Asymmetries
J. P. Ma, G. P. Zhang
The collinear factorization at twist-3 for Drell-Yan processes is studied with the motivation to solve the discrepancy in literature about the single spin asymmetry in the lepton a…
QCD Corrections of All Structure Functions in Transverse Momentum Dependent Factorization for Drell-Yan Processes
J. P. Ma, G. P. Zhang
We study the one-loop correction in Transverse-Momentum-Dependent(TMD) factorization for Drell-Yan processes at small transverse momentum of the lepton pair. We adopt the so-called…
Azimuthal Dependence of DIS with Spin-1 Target
J. P. Ma, C. Wang, G. P. Zhang
We study DIS with a spin-1 hadron or a nucleus polarized in arbitrary direction. The differential cross-section in this case will have an azimuthal dependence. We derive the depend…
QCD Evolutions of Twist-3 Chirality-Odd Operators
J. P. Ma, Q. Wang, G. P. Zhang
We study the scale dependence of twist-3 distributions defined with chirality-odd quark-gluon operators. To derive the scale dependence we explicitly calculate these distributions…
Single Spin Asymmetry in Lepton Angular Distribution of Drell-Yan Processes
J. P. Ma, G. P. Zhang
We study the single spin asymmetry in the lepton angular distribution of Drell-Yan processes in the frame work of collinear factorization. The asymmetry has been studied in the pas…
