The quark-parton model is still at the basis of most of our attempts to describe hadronic
phenomena. It is surprising that a model with essentially noninteracting parts describes so …

In this paper we survey methods by which supersymmetry (or other new physics) could be
observed in experiments at present and future accelerators. We review some of the …

A novel derivation of the Q 2 dependence of quark and gluon densities (of given helicity) as
predicted by quantum chromodynamics is presented. The main body of predictions of the …

The Kadanoff theory of scaling near the critical point for an Ising ferromagnet is cast in
differential form. The resulting differential equations are an example of the differential …

This paper describes the conclusions that can be drawn from the data taken thus far with the
PHOBOS detector at RHIC. In the most central Au+ Au collisions at the highest beam energy …

Asymptotically free gauge theories of the strong interactions are constructed and analyzed.
The reasons for doing this are recounted, including a review of renormalization-group …

Resonance properties are investigated within the QCD-based approach to resonance
physics developed earlier. We extend first the dispersion charmonium theory to include …

It is suggested that a unifying description of leptons and hadrons can be obtained within a
nonabelian gauge theory where the gauge group is a symmetry group of a set of massless …

We explore the implications for hadron spectroscopy of the" standard" gauge model of weak,
electromagnetic, and strong interactions. The model involves four types of fractionally …
