Description

Exclusive Vector Meson Production in the SIDIS kinematic Regime at Hall B of Jefferson Lab provides a unique opportunity to probe the 3D structure of the nucleon through Generalized Parton Distribution Functions (GPDs). Furthermore, by studying this production mechanism we can better understand the background to SIDIS measurements that lead to the same final state. In the channel $ep\rightarrow e\rho^+n$, the $\rho^+$ Meson decays into $\pi^+$ and $\pi^0$, which leads to the final state of $\pi^+ \gamma\gamma n$. The detection of photons and identification of the rho signal presents special challenges to this analysis. In this presentation, I will describe current progress using different techniques to extract Beam Spin Asymmetries (BSAs) for this channel.
