Instantons in QCD
Thomas Schäfer,Edward Shuryak +1 more
TL;DR: In this article, the authors review the theory and phenomenology of instantons in quantum chromodynamics (QCD) and provide a pedagogical introduction to semiclassical methods in quantum mechanics and field theory.
Journal ArticleDOI
Glueballs, Hybrids, Multiquarks. Experimental facts versus QCD inspired concepts
TL;DR: In this article, it was shown that the meson σ and κ mesons exhibit a spectrum of (squared) masses which are proportional to the sum of orbital angular momentum and radial quantum numbers.

QCD forces and heavy quark bound states
TL;DR: In this article, the present knowledge of QCD confining forces between static test charges is summarised, with an emphasis on lattice results, and the validity of non-relativistic QCD and the adiabatic approximation with respect to heavy quark bound states is explored.

TL;DR: In this paper, the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment, are highlighted, highlighting how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as searches for physics beyond the Standard Model.

QCD and instantons at finite temperature
TL;DR: In this article, the authors present a topological classification of finite-energy, periodic fields and the classical solutions which minimize the action in each topological sector are examined and the effects of instantons can be reliably calculated at sufficiently high temperature.
Journal ArticleDOI
Topology of Higgs fields
TL;DR: In this paper, it was shown that the conserved magnetic charge discovered by ’t Hooft in non−Abelian gauge theories with spontaneous symmetry breaking is not associated with the invariance of the action under a symmetry group.

Nonperturbative Length Scale in High Temperature {QCD}
TL;DR: The string tension of spacelike Wilson loops is computed in SU(3) lattice gauge theory in the high-temperature deconfined phase and an upper bound for the length scale where nonperturbative fluctuations become dominant is computed.

The Topological Mechanism for Permanent Quark Confinement in a Non-Abelian Gauge Theory
TL;DR: In this paper, it was shown that superconductivity is an absolute phenomenon, the conductivity is rigorously zero, and quarks are permanently confined in a non-Abelian theory enriched with Dirac magnetic monopoles.
