Abstract

This work studies the target-spin asymmetry from the EG1-DVCS experiment conducted in Hall B of Jefferson National Lab using the Continuous Electron Beam Accelerator Facility’s 6 GeV electron beam, a longitudinally polarized solid-state (¹⁴N H₃ ) target, and the CEBAF Large Acceptance Spectrometer equipped with an additionally built Inner Calorimeter. The high statistics collected allow for detailed studies of the Q² , x_B and t dependencies of the DVCS amplitude over a wide range of kinematics. This measurement, in combination with the measurement of the beam spin asymmetry and double spin asymmetry allows for extraction of GPD related quantities, Compton Form Factors: Re(H), Im(H), Re(~/H), and Im(~/H).
