Abstract

We consider the process gamma^* N -> M₁ M₂ N' with a large rapidity gap between the two mesons M₁ and M₂. Within the QCD collinear approximation, the scattering amplitude may be written as a convolution of an impact factor describing the gamma^* -> M₁ transition and an amplitude describing the N -> M₂ N' collinear process.
