Exclusive photoproduction of a di-meson pair with large invariant mass
We consider the exclusive photoproduction of a di-meson pair with large invariant mass, γN → N ′ M1 M2 , in the framework of collinear factorisation. The mesons considered M1 and M2 are either pions or rho mesons, charged or neutral. We consider the kinematic regime characterised by a large invariant mass of the two-me...
