Factorization and Non-factorization in Diffractive Hard Scattering
Factorization, in the sense defined for inclusive hard scattering, is discussed for diffractive hard scattering. A factorization theorem similar to its inclusive counterpart is presented for diffractive DIS. For hadron-hadron diffractive hard scattering, in contrast to its inclusive counterpart, the expected breakdown of factorization is discussed. Cross section estimates are given from a simpl...
متن کاملSaturation 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...
متن کاملThe stationary phase point method for transitional scattering: diffractive radio scintillation
The stationary phase point (SPP) method in one-dimensional case is introduced to treat the diffractive scintillation. From weak scattering, where the SPP number N=1, to strong scattering (N≫1), via transitional scattering regime (N∼2,3), we find that the modulation index of intensity experiences the monotonically increasing from 0 to 1 with the scattering strength, characterized by the ratio of...
متن کاملHard scattering factorization and light cone hamiltonian approach to diffractive processes
We describe diffractive deeply inelastic scattering in terms of diffractive parton distributions. We investigate these distributions in a hamiltonian formulation that emphasizes the spacetime picture of diffraction scattering. For hadronic systems with small transverse size, diffraction occurs predominantly at short distances and the diffractive parton distributions can be studied by perturbati...
متن کاملPhoton 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.
