DUAL PARTON MODEL

Physics Reports, 1988
Soft multiparticle production is a dominant feature of most events in high energy hadronic collisions. Since soft processes have no large momentum transfer, perturbative QCD expansions in the strong coupling constant are not applicable. However, suitable large N expansions of QCD provide a topological classification of diagrams and a potentially useful

Photonic parton distributions

Physical Review D, 1992
The quark and gluon distributions of the photon are determined in leading and higher order by imposing a vector-meson dominance (VMD) valencelike structure at a low resolution scale adopted from the pion. This leaves only one free parameter, not sufficiently constrained by VMD, to be fixed by experiment.

Partons in nuclei

Physical Review D, 1986
We study the different explanations of the European Muon Collaboration effect. Although the theoretical models are very sensitive to input free-nucleon structure functions, we find that each has distinctive testable traits. Therefore, we examine different reactions to see which can distinguish the models.

Quantum statistical parton distributions

Journal of Physics A: Mathematical and General, 2002
Summary: Modified Fermi-Dirac functions for the fermionic partons and a Bose-Einstein expression for gluons allow us to successfully describe both polarized and unpolarized structure functions in terms of a small number of parameters. Definite predictions are made for \(\bar q\) distributions to be tested in forthcoming experiments.
