Effective field theories for heavy quarkonium
TL;DR: In this paper, a coherent field-theory-derived quantum-mechanical scheme was proposed to calculate the properties of bound states made by two or more heavy quarks.
Journal ArticleDOI
Bound states of quarks
TL;DR: In this article, a review of the potential-model approach is presented, together with a brief survey of the motivations for various potential models and the application of the developed theoretical framework.
Journal ArticleDOI
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.

Wormholes in AdS
Juan Maldacena,Liat Maoz +1 more
TL;DR: In this paper, a few euclidean supergravity solutions with multiple boundaries were constructed, where the corresponding boundary field theory is well defined on each boundary, and these configurations are puzzling from the AdS/CFT point of view.

Symmetry-breaking aspects of the roughening transition in gauge theories
TL;DR: In this article, it was shown that the associated Goldstone bosons live effectively in 1 + 1 dimensions and therefore, by the Mermin-Wagner-Coleman theorem, destabilize the flux tube.

Spin-Dependent Forces in Heavy-Quark Systems
Estia Eichten,Frank L. Feinberg +1 more
TL;DR: In this article, the Coulomb plus linear potential model was used to obtain spin-dependent forces for heavy bound states in quantum chromodynamics, where the spin-orbit and Thomas precession terms were expressed in terms of the static energy, assuming that the confinement mechanism is electric.

One-loop perturbative calculation of Wilson loops on finite lattices
U. Heller,Frithjof Karsch +1 more
TL;DR: In this article, the expectation values of Wilson loops and Polyakov lines on finite asymmetric lattices have been investigated. But the one-loop (order g 4 ) perfturbative calculation of expectation values has not been considered.

Another connection between the Λ parameters of the euclidean lattice and continuum QCD
TL;DR: In this article, the relation between the lattice and the short-distance q q -force Λ parameters was computed, and the result of this perturbative computation was in striking agreement with the Creutz Monte Carlo estimate.
Journal ArticleDOI
Monte Carlo calculation of the spin-dependent potentials for heavy-quark spectroscopy.
TL;DR: A long-range nonperturbative component in one of the spin-orbit potentials is found, whereas all other potentials exhibit a short-ranged perturbative behavior.
