摘要
Generalized Parton Distributions (GPDs) provide a way to access total angular momenta of partons and give a multidimensional picture of the nucleon structure Deeply Virtual Compton Scattering (DVCS) is the most direct exclusive process to study GPDs Different azimuthal cross-section asymmetries with respect to beam helicity, beam charge, and target. polarization have been measured in the HERMES experiment A recoil detector was installed at HERMES to directly detect the recoil proton
