The partonic structure of the generalized BFKL Pomeron (original) (raw)

We report on QeD calculation of the cross section of diffractive DIS and of the partonic structure of the Pomeron in the generalized BFKL model. Our main result is that the Pomeron cannot be treated as a particle with uniquely defined structure function and flux from the proton. In fact different fluxes must be defined for the sea and the valence components. Furthermore, the fluxes for the charm and longitudinal valence component are different from the previous ones and cannot be defined as {3 and Q2 independent respectively. Diffractive Deep Inelastic Scattering can be understood (if one assumes single pomeron exchange) as DIS on Pomerons radiated by protons.
