Diffractive Hard Scattering
Diffraction is an old subject which has received much interest in recent years due to the advent of diffractive hard scattering. We discuss some theoretical models and experimental results that have shown new striking effects, e.g. rapidity gaps in jet and W production and in deep inelastic scattering. Many aspects can be described through the exchange of a pomeron with a parton content, but th...
متن کاملProof of Factorization for Diffractive Hard Scattering
A proof is given that hard-scattering factorization is valid for deep-inelastic processes which are diffractive or which have some other condition imposed on the final state in the target fragmentation region.
متن کاملDiffractive Hard Scattering with a Coherent Pomeron
Diffractive scattering involves exchange of a Pomeron to make a rapidity gap. It is normally assumed that to get a hard scattering in diffraction, one may treat the Pomeron as an ordinary particle, which has distributions of gluons and quarks. We show that this is not so: When we use perturbative QCD, there is a breakdown of the factorization theorem. The whole Pomeron can initiate the hard sca...
متن کاملHard diffractive Photon-Proton Scattering at large t
We propose to test perturbative QCD in the Regge limit by means of diffractive photon scattering γp → γX at large t and very high energies W 2 |t| ΛQCD. The helicity amplitudes of this process were calculated using the Lipatov solution of the BFKL equation for t 6= 0. We found that the perturbatively calculated cross section for this process exceeds the cross section for J/Ψ photoproduction ass...
متن کاملFactorization 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...
