p 요약 :The Generalized Parton Distributions (GPDs) provide a new description of the complex internal structure of the nucleon in terms of its elementary constituents, the quarks and the gluons. Jefferson lab (JLab) in Hall-A high precision spectrometer and a compact, hermetic high-performance PbF2 calorimeter allows us to obtain high statistics absolute measurements of Deep Virtual Compton Scattering (DVCS) cross-sections in a wide kinematic domain with CEBAF 6 and 12GeV. In particular, the data from 12GeV precision measurements allow us to extract three Twist-2 and two Twist-3 observables. In this talk, I will very briefly introduce the GPDs physics program in Hall-A, and news for currently running 12GeV experiment in the Hall-A. I will also demonstrate a GEANT4-MC (GEMC) simulation for JLab version Electron Ion Collider as future facility.
