Diffractive Dis from the Generalized Bfkl Pomeron. Predictions for Hera

We present microscopic QCD calculation of the cross section of diffractive DIS and of the partonic structure of the pomeron from the dipole approach to the generalized BFKL pomeron. We show that the pomeron can not be treated as a particle with uniquely defined structure function and flux in the proton. We find strong factorization breaking which can approximately be described by the two-component structure function of the pomeron, each component endowed with the different flux of pomerons in the proton. We predict very weak Q dependence of the diffractive contribution to the proton structure function. E-mail: [email protected]
