Revealing transversity GPDs through the photoproduction of a photon and a rho meson

Résumé

Photoproduction of a pair of particles with large invariant mass is a natural extension of collinear QCD factorization theorems which have been much studied for deeply virtual Compton scattering and deeply virtual meson production. We discuss the production of a photon and a meson, where the wide angle Compton scattering on a meson subprocess factorizes from generalized parton distribution. We calculate at dominant twist and leading order in alpha_s, the production cross-section of a transversely polarized rho meson which is sensitive to chiral-odd GPDs, and show that it may be measurable in near future JLab experiments.
