On the Singular Behavior of the Chirality-Odd Twist-3 Parton Distribution e(x)
J. P. Ma, G. P. Zhang
The first moment the chirality-odd twist-3 parton distribution is related to the pion-nucleon -term which is important for phenomenology. However, the possible existence…
Gluon GPDs and Exclusive Photoproduction of a Quarkonium in Forward Region
Z. L. Cui, M. C. Hu, J. P. Ma
Forward photoproduction of can be used to extract Generalized Parton Distributions(GPD's) of gluons. We analyze the process at twist-3 level and study relevant classification…
Reply to "the Comment on `Gauge Invariance and kT-Factorization of Exclusive Processes'"
F. Feng, J. P. Ma, Q. Wang
A new method is proposed to calculate wave functions in -factorization in \cite{LiMi} as a comment about our paper \cite{FMW}. We point out that the results obtained with the…
Gauge Invariance and k_T-Factorization of Exclusive Processes
F. Feng, J. P. Ma, Q. Wang
In the -factorization for exclusive processes, the nontrivial -dependence of perturbative coefficients, or hard parts, is obtained by taking off-shell partons. This bring…
Transverse-Momentum Dependent Factorization for gamma^* pi^0 to gamma
J. P. Ma, Q. Wang
With a consistent definition of transverse-momentum dependent (TMD) light-cone wave function, we show that the amplitude for the process can be factorized when the v…
On Two-Body Decays of A Scalar Glueball
K. T. Chao, X. G. He, J. P. Ma
We study two body decays of a scalar glueball. We show that in QCD a spin-0 pure glueball (a state only with gluons) cannot decay into a pair of light quarks if chiral symmetry hol…
