In this contribution I would like to report on our recent computation [1,2] on exclusive C-even charmonia productions in high-energy electron-proton collisions. The C-even charmonia states serve as a probe of the odderon amplitude in the proton which is an off-forward generalized transverse momentum distribution formed by at least three gluons in a C-odd state. We are motivated by the odderon...
In this talk, I will present our recent results for the kinematic corrections beyond the twist-four accuracy to the
deeply-virtual Compton scattering (DVCS) of a spin-1/2 target. Phenomenologically, such corrections are crucial for
removing the reference frame dependence when extracting the generalized parton distribution (GPD) from experimental
data. Theoretically, the kinematic...
We give an overview of recent developments in the computation of the anomalous dimension matrix of composite operators in non-forward kinematics. The elements of this matrix determine the scale dependence of non-perturbative parton distributions, such as GPDs, and hence constitute important input for phenomenological studies of exclusive processes like deeply-virtual Compton scattering....
