GPDs measurement using DVCS process at ENC/FAIR — •Donghee Kang — Institut für Kernphysik, Universität Mainz, Germany

Generalized Parton Distributions (GPDs) describe simultaneously distributions for the transverse position and longitudinal momentum of partons inside the nucleon. The Deeply Virtual Compton Scattering (DVCS) process on the proton, ep → e′p′γ, is the simplest and pormising reaction channel to access GPDs. An Electron Nucleon Collider (ENC) using the High Energy Storage Ring (HESR)/FAIR and utilizing the high resolution PANDA spectrometer is proposed to investigate the DVCS process. We demonstrate this specific advantage from the collider kinematic. In a feasibility study, we have estimated the acceptance and resolution for the DVCS process assuming 15 GeV proton beam and 3 GeV electron beam in collision.
