Inclusive Diffraction at Hera

Diffraction at HERA, the Tevatron and the LHC

In these lectures, we present and discuss the most recent results on inclusive diffraction from the HERA and Tevatron colliders and give the prospects for the future at the LHC. Of special interest is the exclusive production of Higgs boson and heavy objects (W , top, stop pairs) which will require a better understanding of diffractive events and the link between ep and hadronic colliders, as w...

Review of High Energy Diffraction in Real and Virtual Photon Proton scattering at HERA

The electron-proton collider HERA at DESY opened the door for the study of diffraction in real and virtual photon-proton scattering at center-of-mass energies W up to 250 GeV and for large negative mass squared −Q2 of the virtual photon up to Q = 1600 GeV. At W = 220 GeV and Q = 4 GeV, diffraction accounts for about 15% of the total virtual photon proton cross section decreasing to ≈ 5% at Q = ...

Experimental Studies of Diffractive Processes at Hera

Diffractive processes in photon-proton interactions at HERA offer the opportunity to improve the understanding of the transition between the soft, non-perturbative regime in hadronic interactions at Q2 = 0 and the perturbative region at high Q2. Recent experimental results from HERA on inclusive diffractive scattering, exclusive vector meson production and the properties of the hadronic final s...

4 Ju n 20 02 INCLUSIVE DIFFRACTION AT HERA

The diffractive dissociation of virtual photons, γ * p → Xp, has been studied in ep interactions at HERA with the H1 and ZEUS detectors. The data are presented in terms of the diffractive structure function F D 2 and of the diffractive cross sections dσ/dt and dσ/dMX. The t-dependence of the cross section is measured. The Pomeron intercepts extracted from diffractive and inclusive ep interactio...
