Exclusive electroproduction of pions at Hall A, Jefferson Lab

Generalized Parton Distributions (GPDs) provide simultaneous spatial and momentum distribution of quarks and gluons inside the nucleons . GPDs can be accessed experimentally through hard exclusive processes like Deeply Virtual Compton Scattering (DVCS) or Deeply Virtual Meson Production (DVMP). Experiment E12-06-114 completed its data taking at the end of 2016 in Hall A at JLab. Main goal of this experiment is to measure the DVCS and exclusive $\pi^0 $ electroproduction cross-sections at various $Q^2$ for three Bjorken-x in valence regime. These result will provide stringent test of QCD factorization in hard exclusive processes over a wide range of $Q^2$ achieved with upgraded CEBAF to 12 GeV. I will show the most recent results for exclusive $\pi^0 $ electroproduction at high Bjorken-x (0.60).
