Deep inelastic scattering and “elastic” diffraction

Connection between Inelastic Proton-proton Reactions and Deep Inelastic Electron Scattering*

Following the idea that the electromagnetic and nuclear distributions behave similarly for large momentum transfers (as introduced by Wu and Yang and further developed by A.barbanel, Drell and Gilman) we examine the possibility of relating the deep inelastic electron scattering to large momentum transfer and high energy inelastic protonproton reactions.

Inelastic Hadron Diffraction in High Energy Elastic Scattering of Nuclei

Inelastic hadron diffraction refers to quasi-elastic transitions in which the colliding particles conserve their dominant quantum numbers. High energy of collision facilitates to satisfy the condition of coherence thus assuring that interaction does not change the character of the particles. High energy elastic scattering of hadrons is thus generally built of: i) elastic diffraction which resul...

v 1 4 D ec 1 99 5 Small x physics in deep inelastic lepton scattering

The perturbative QCD predictions concerning deep inelastic scattering at low x are summarized. The theoretical framework based on the leading log 1/x resumma-tion and k t factorization theorem is described. The role of studying final states in deep inelastic scattering for revealing the details of the underlying dynamics at low x is emphasised and some dedicated measurements, like deep inelasti...

Elastic and Inelastic Scattering in Electron Diffraction and Imaging Introduction

Kinematical rainbow and elastic focusing effects in atom-surface scattering

In this work two general anomalous singularity effects in elastic surface diffraction are reported. First, a kinematical rainbow ~KR! condition, a special case of the well-known rainbow singularity, is examined and shown to be a two-dimensional counterpart of the glory effect in gas-phase scattering. Second, an elastic focusing ~EF! effect is presented as the elastic counterpart of a general ef...

The Pomeron in Exclusive J/ψ Vector Meson Production

Elastic production of vector mesons in electronproton interaction has provided a deeper understanding of the diffraction phenomenon and finds a sensible description in a variety of models. The first attempts to describe diffractive photoproduction were based on vector dominance model [1] and Regge theory [2]. Since various aspects of the deep inelastic scattering and of elastic processes are bo...
