Diffractive Phenomena at HERA 1
Highlights selected from recent measurements of colour-singlet exchange processes at HERA are summarised. Particular emphasis is placed on energy and momentum transfer dependences and the decomposition of the data into an expansion in Regge trajectories. The latest results in vector meson helicity analysis, partonic descriptions of hard diffraction and diffractive dijet production are also cove...
متن کاملResults on Diffraction at Hera and Tevatron
Recent results on diffraction at HERA, from the H1 and ZEUS Collaborations, and at Tevatron, from the CDF and D0 Collaborations, are reviewed. The measurement of the diffractive structure function at HERA is presented, and the pomeron structure function is extracted from QCD fits. Diffractive dijet production is given as an example analysis of the diffractive final state. These analysis are con...
متن کاملMeasurements of the Diffractive Structure Function F D ( 3 ) 2 ( β , Q 2 , x IP ) at HERA
Recent measurements of the diffractive cross section in deep-inelastic scattering (DIS) at HERA are presented. The data are used to investigate the factorisation properties of diffractive DIS and to examine its quantum chromodynamic (QCD) structure. Models based on the colour dipole approach to DIS are also tested. 1. Diffractive Deep Inelastic Scattering At low x in DIS at HERA, approximately ...
متن کاملFinal States in Diffraction at HERA
Recent experimental results on diffractive high ET jet production and diffractive open charm production, obtained by the H1 and ZEUS experiments at HERA, are presented. Various theoretical models for diffractive hard scattering are discussed and confronted with the experimental data.
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...
