Description
Since 2018, the CLAS12 experiment located in Hall B at Jefferson National Laboratory, Newport News, VA, USA has collected electron scattering data over a broad kinematic range at beam energies up to 10.6 GeV. A collaboration of CLAS12 physicists from Jefferson Lab, MIT, and Tel Aviv University is developing several analyses of CLAS12 data aimed at extracting new information on the quark and gluon structure of the proton in the valence region via determination of cross sections for deeply virtual exclusive processes, where the additional particle produced in the final state, e.g. $\gamma$, $\pi^0$, $\phi$, is detected in coincidence with the scattered electron and recoil proton. Such cross sections are known to be sensitive to non-forward, nonlocal structure characterized by Generalized Parton Distribution Functions (GPDs) and gravitational form factors. The cross sections for different exclusive final states are measured at several beam energies and presented as functions differential in kinematic variables $Q^2$, $x_B$, $t$, and $\phi$. Current results will be reported and the future perspective presented.
