### Description

Generalized Parton Distributions (GPDs) provide simultaneously 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 half of its data taking at the end of 2016 in Hall A at JLab. This experiment has measured 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 factorization in hard exclusive processes over a wide range of $Q^2$ achieved with 12 GeV upgrade. I will show the most recent results on the behalf of our DVCS collaboration.
