Parton Models and Deep Hadron - Hadron Scattering
We review the recent applications of various parton models, to the problem of hadron-hadron scattering at large momentum transfers. Models which allow direct parton-parton interactions as well as those that do not are considered. Predictions for the structure of hadronic final states (whether or not transverse jets exist), associated multiplicities, and the s and t dependencies of inclusive and...
متن کاملHadron-Hadron Scattering in the Nonrelativistic Quark Model
In this HADRON2001 contribution we summarize the status of our quark-model calculations of hadron-hadron scattering amplitudes in annihilation-free channels. The predictions are in reasonably good agreement with experimentally known S-wave meson-meson and meson-baryon phase shifts, and there are very recent indications that S-wave πω scattering (extracted from FSIs in b1 decay) may also be simi...
متن کاملLocal Quark-hadron Duality in Electron Scattering
We present some recent developments in the study of quark-hadron duality in structure functions in the resonance region. To understand the workings of local duality we introduce the concept of truncated moments, which are used to describe the Q dependence of specific resonance regions within a QCD framework.
متن کاملQuark-Hadron Duality in Electron Scattering
Quark-hadron duality addresses some of the most fundamental issues in strong interaction physics, in particular the nature of the transition from the perturbative to non-perturbative regions of QCD. I summarize recent developments in quark-hadron duality in lepton–hadron scattering, and outline how duality can be studied at future high-luminosity facilities such as Jefferson Lab at 12 GeV or an...
متن کاملQuark-Hadron Duality in Neutrino Scattering
We present a phenomenological model of the quark-hadron transition in neutrino-nucleon scattering. Using recently extracted weak nucleon transition form factors, we investigate the extent to which local and global quark-hadron duality is applicable in the neutrino F1, F2 and F3 structure functions, and contrast this with duality in electron scattering. Our findings suggest that duality works re...
