High order kinematical effects in DVCS for EIC
ORAL
Abstract
We apply the frame-independent deeply virtual Compton scattering cross-section formula to the EIC kinematics and study the high order kinematical effects, including both kinematical higher-twist effects, corrections from higher-twist CFFs and quantum loop corrections to the next-to-leading order of strong coupling. We show how those effects compared with the leading order contribution, which plays an important role in extracting the leading twist Compton form factors with precision.
