QCD 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 ...
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 کاملAspects of the confinement mechanism in Coulomb-gauge QCD.
Phenomenological consequences of the infrared singular, instantaneous part of the gluon propagator in the Coulomb gauge are investigated. The corresponding quark Dyson-Schwinger equation is solved, neglecting retardation and transverse gluons and regulating the resulting infrared singularities. While the quark propagator vanishes as the infrared regulator goes to zero, the frequency integral ov...
متن کاملHamiltonian approach to Coulomb gauge Yang-Mills Theory
The vacuum wave functional of Coulomb gauge Yang-Mills theory is determined within the vari-ational principle and used to calculate various Green functions and observables. The results show that heavy quarks are confined by a linearly rising potential and gluons cannot propagate over large distances. The 't Hooft loop shows a perimeter law and thus also indicates confinement.
