Nonlinear Pomeron trajectory in diffractive deep inelastic scattering.

Charm production in diffractive deep inelastic scattering

The diffractive open charm production is computed in perturbative QCD formalism and in the Regge approach. The results are compared with recent data on charm diffractive structure function measured at DESY-HERA. Our results demonstrate that this observable can be useful to discriminate the QCD dynamics.

Photon Polarisation in Diffractive Deep Inelastic Scattering

The distribution of a suitably defined azimuthal angle in diffractive deep inelastic scattering contains information on the polarisation of the exchanged photon. In particular it allows one to constrain the longitudinal diffractive structure function. We investigate the potential of such bounds in general and for particular diffractive final states.

Deep Inelastic Electron–Pomeron Scattering at HERA

The idea that the pomeron has partonic structure similar to any other hadron has been given strong support by recent measurements of the diffractive structure function at HERA. We present a detailed theoretical analysis of the diffractive structure function under the assumption that the diffractive cross section can be factorized into a pomeron emission factor and the deep inelastic scattering ...

Saturation in Diffractive Deep Inelastic Scattering

We successfully describe the HERA-data on diffractive deep inelastic scattering using a saturation model which has been applied in our earlier analysis of the inclusive ep-scattering data. No further parameters are needed. Saturation already turned out to be essential in describing the transition from large to small values of Q2 in inclusive scattering. It is even more important for diffractive...
