Secondary Reggeons in Diffractive Deep Inelastic Scattering - the Microscopic QCD Evaluation

Abstract

We present the microscopic QCD evaluation of the secondary reggeon contribution to diffractive DIS. It is shown that the interference between Pomeron and Reggeon enters in the maximal possible way. In the region of large ${\hat{I}}^2\simeq 1$ it is shown, that the structure functions of the Reggeon and Pomeron as well as the Reggeon-Pomeron interference SF have a universal $\sim (1-{\hat{I}}^2{)}^2$ behaviour.
