Description

In the framework of collinear QCD factorization, we study the
photoproduction of a gamma meson pair with a large invariant mass and a small transverse momentum, as a new way to access generalized parton distributions (GPDs), in both chiral-even and chiral-odd sectors. In the kinematics of JLab~12-GeV, we demonstrate the feasibility of this measurement.
