نویسنده
چکیده
Recent developments in Quantum Chromodynamics (QCD) are reviewed on three major topics where nonper-turbative gluon excitations of the QCD vacuum and the physical properties of the confining flux play a central role: (1) New lattice results on the spectrum and wave functions of heavy QQgluon molecules, known as heavy hybrids, will be discussed. (2) Recent advances on the glueball spectrum in lattice QCD will be presented with some theoretical observations. (3) Progress in our understanding of the nonperturbative internal structure of the confining flux and its excitation spectrum will be reported.

The spherically and cylindrically symmetric solutions of the SU (3) Yang-Mills theory are obtained. The corresponding gauge potential has the confining properties. It is supposed that: a) the spherically symmetric solution is a field distribution of the classical " quark " and in this sense it is similar to the Coulomb potential; b) the cylindrically symmetric solution describes a classical fie...

Experimental rates of W and dijets diffractively produced at the Tevatron Collider have recently become available. We use parametrizations of the pomeron structure function obtained from HERA data by two different schemes to compare theoretical expectations with the measured rates.

The background field formalism is used to implement nonpertur-bative QCD contributions into diagrammatic technic at T > 0. The leading terms both in the confining and nonconfining phase are identified at large N c and the transition temperature is calculated in this limit, which appears to be in good agreement with the Monte Carlo calculations.
