Target Single Spin Asymmetry in DVCS

ORAL

Abstract

The target single spin asymmetry in the reaction ep$\rightarrow$ ep$\gamma$ is directly proportional to the imaginary part of the Deeply Virtual Compton Scattering (DVCS) amplitude and gives access to a combination of the Generalized Parton Distributions (GPDs) \~H, H, and E. We present the preliminary single spin asymmetry studies from the eg1-dvcs experiment conducted in Hall B of Jefferson Lab using the Continuous Electron Beam Accelerator Facility's (CEBAF) 6 GeV electron beam, a polarized solid-state \(^{14}NH_{3}\) target, and the CEBAF Large Acceptance Spectrometer (CLAS) equipped with an additionally built Inner Calorimeter (IC). The high statistics collected allow for detailed studies of the Q\(^2\), x\(_B\) and t dependences of the DVCS amplitude over a wide range of kinematics.
