General Parton Distributions and Counting of Helicity-Flip Nucleon Form Factors
Zhang Chen
We give a brief overview of the General Parton Distributions(GPDs), including their properties, connections to conventional quantities, and relationships to physical observables. W…
Counting and Tensorial Properties of Twist-Two Helicity-Flip Nucleon Form Factors
Zhang Chen, Xiangdong Ji
We perform a systematic analysis on the off-forward matrix elements of the twist-two quark and gluon helicity-flip operators. By matching the allowed quantum numbers and their cros…
Deeply Virtual Compton Scattering and Skewed Parton Distribution
Zhang Chen
An overview of the current status of and possible future theoretical, phenomenological and experimental studies of DVCS and SPD's is presented.
Virtual Compton Scattering at High Energy
Zhang Chen
In this dissertation we develop a theoretical framework in the context of perturbative QuantumChromoDynamics (pQCD) for studying non-forward scattering processes. In particular, we…
Non-Forward and Unequal Mass Virtual Compton Scattering
Zhang Chen
We discuss the general operator product expansion of a non-forward unequal mass virtual compton scattering scattering amplitude. We find that the expansion now should be done in do…
