Unitarity effects in hard diffraction at HERA
نویسنده
چکیده
We study how factorization breaking changes when going from diffractive deep inelastic scattering to diffractive photoproduction of dijets. These processes offer a sensitive probe of the interplay of soft and hard mechanisms in QCD. We demonstrate that unitarity effects are already important in the gluon distribution for x ∼ 10 −4, for quite a wide range of Q2.

General Issues in Small - x and Diffractive
A selected review of topics at the border of hard and soft physics is given. Particular emphasis is placed on diffraction dissociation at Fermilab and HERA. Recently, significant differences between diffraction dissociation at HERA and at Fermilab have become apparent. This may suggest that one already is reaching nonlinear (unitarity) effects which are extending from the soft physics region in...
متن کاملResults on Hard Diffractive Production
The results of experiments at hadron colliders probing the structure of the pomeron through hard diffraction are reviewed. Some results on deep inelastic diffractive scattering obtained at HERA are also discussed and placed in perspective. By using a properly normalized pomeron flux factor in single diffraction dissociation, as dictated by unitarity, the pomeron emerges as a combination of vale...

New experimental data from HERA explore the region of very small x and small and moderate Q 2. We study the role of unitarity corrections in the description of these data. For that, we propose a model separating the small and large components of the q ¯ q fluctuation. This model gives a unified description of total and diffractive production in γ * p interactions. In this model unitarity correc...
متن کاملFuture Diffraction at HERA
Future prospects of hard diffraction at HERA a reviewed. A selection of processes which can be calculated in pQCD is given, with emphasis on the separation of soft and hard diffraction. The main focus will be put on the energy dependence of diffractive processes and signatures for the hard pQCD pomeron. Problems in the experimental detection of these processes and the expected significance of f...
متن کاملMultiparticle Production in High-mass Diffraction Dissociation and the Interplay of Photons and Pomerons
Multiple interaction models satisfying s-channel unitarity predict that, in contrast to inelastic processes, factorization is violated in diffractive processes. The size of this effect can be characterized in terms of the rapidity gap survival probability. The possibility of its measurement at HERA is pointed out. Furthermore a method to measure photon diffraction dissociation at LEP2 and plann...
