Coulomb gauge Gribov copies and the confining potential
We develop an approach to the static inter-quark potential based on Polyakov lines of finite temporal extent, evaluated in Coulomb gauge. At small spatial separations, the potential can be understood as being between two separately gauge invariant colour charges. At larger separations Gribov copies obstruct the non-perturbative identification of individually gauge invariant colour states. We sh...
متن کاملCoulomb - gauge in QCD : renormalization and confinement ∗
We review the Coulomb gauge in QCD and report some recent results. The minimal Coulomb gauge is defined and the fundamental modular region, a region without Gribov copies, is described. The Coulomb gauge action is expressed in terms of the dynamical degrees of freedom with an instantaneous Coulomb interaction, and its physical meaning is discussed. The local Coulomb gauge action with phase-spac...
متن کاملMesons and diquarks in Coulomb-gauge QCD
I demonstrate how confinement in Coulomb-gauge QCD makes quark-quark states of the color anti-triplet (diquarks) move out of the physical spectrum. Mesons as color singlet quark-antiquark states, on the other hand have finite masses and for highly excited states in the meson spectra effective restoration of chiral symmetry can be observed. In Coulomb-gauge QCD the 00-component of the gluon prop...
متن کاملInvestigation of light and heavy tetraquark candidates using lattice QCD
We review the status of an ongoing long-term lattice investigation of the spectrum and structure of tetraquark candidates. We focus on the light scalar meson a0(980). First steps regarding the study of a possibly existing ccc̄c̄ tetraquark are also outlined.
متن کاملQCD Coulomb Gauge Approach to Exotic Hadrons
The Coulomb gauge Hamiltonian model is used to calculate masses for selected J states consisting of exotic combinations of quarks and gluons: ggg glueballs (oddballs), qq̄g hybrid mesons and qq̄qq̄ tetraquark systems. An odderon Regge trajectory is computed for the J−− glueballs with intercept much smaller than the pomeron, explaining its nonobservation. The lowest 1 hybrid meson mass is found to ...
