Diffractive electroproduction of two mesons separated by a large rapidity gap

By D.Yu. Ivanov, B. Pire, L. Szymanowski and O.V. Teryaev


We consider the process gamma^* N -> M_1 M_2 N' with a large rapidity gap between the two mesons M_1 and M_2. Within the QCD collinear approximation, the scattering amplitude may be written as a convolution of an impact factor describing the gamma^* -> M_1 transition and an amplitude describing the N -> M_2 N' collinear process
