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...
متن کاملInclusive Diffraction at Hera
New precision measurements of inclusive diffractive deep-inelastic ep scattering interactions, performed by the H1 and ZEUS collaborations at the HERA collider, are discussed. A new set of diffractive parton distributions, determined from recent high precision H1 data, is presented.
متن کاملReview 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 = ...
متن کاملExperimental 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...
متن کامل4 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...
