Accessing chiral-even quark generalised parton distributions in the exclusive photoproduction of a γπ ± pair with large invariant mass in both fixed-target and collider experiments

Accessing chiral-even quark generalised parton distributions in the exclusive photoproduction of a γπ ± pair with large invariant mass in both fixed-target and collider experiments

Abstract We compute the exclusive photoproduction of a γπ ± pair using the collinear factorisation framework, in the kinematic regime where the pair has a large invariant mass and the meson has a sufficiently large transverse momentum to not resonate with the outgoing nucleon. This exclusive channel...
