Quark-Antiquark Production in DIS Diffractive Dissociation
We calculate the cross section for the production of two jets with large transverse momenta k in DIS diffractive dissociation for both transverse and longitudinally polarized photons. The scale which defines the hardness of the Pomeron is found to be k Q 2 +M M . We present analytic expressions and discuss numerical results relevant for the diffractive dissociation at HERA. 1.) The diffractive ...
متن کاملQuark-Antiquark Jets in DIS Diffractive Dissociation
We report on investigations concerning the production of large transverse momentum jets in DIS diffractive dissociation. These processes constitute a new class of events that allow for a clean test of perturbative QCD and of the hard (perturbative) pomeron picture. The measurement of the corresponding cross sections might possibly serve to determine the gluon density of the proton.
متن کاملA Parton Model for Diffractive Processes in Deep Inelastic Scattering
We demonstrate that the global properties of the “rapidity gap” events, observed at HERA, can be understood based on electron-gluon scattering as the underlying partonic process. Using the measured inclusive structure function F2 to determine the parameters of the parton model, the diffractive structure function F 2 is predicted. The ratio of diffractive and inclusive cross sections, RD = σD/σi...
متن کاملAzimuthal Dependence in Diffractive Processes
Azimuthal distributions in high-energy processes give information about the helicity structure of diffractive reactions. I discuss predictions of several dynamical mechanisms in this context, both for electron-proton and for hadron-hadron collisions. 1 Azimuthal distributions in ep diffraction In this talk I give several examples of what azimuthal distributions can tell us about diffractive int...
متن کاملDiffractive Processes at the LHC
We consider diffractive processes which can be measured at the LHC. Analysis of diffractive events will give unique information about the high energy asymptotics of hadron scattering. In semihard diffraction one may study the partonic structure of the Pomeron. Central Exclusive Diffractive production provides a possibility to investigate the new particles (Higgs bosons, SUSY particles,...) in a...
