Abstract

We discuss the factorization breaking effects caused by the contribution to large rapidity gap events from DIS on secondary reggeons. Based on the triple-Regge phenomenology of hadronic diffraction dissociation, we present estimates for the flux and structure function of the f reggeon. The kinematical x_Pom-beta correlation is shown to modify substantially the observed x_Pom dependence of the diffractive structure function. The secondary reggeon and x_Pom-beta correlation effects explain the recent H1 finding of the factorization breaking and resolve the apparent contradiction between the preliminary H1 results and predictions from the color dipole gBFKL approach. We suggest further tests of predictions for diffractive DIS from the gBFKL approach.
