Coulomb - 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 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 ...
متن کامل0 The Coulomb Phase Revisited
Motivated by the forthcoming data from the E950 experiment at BNL for small angle polarized proton-carbon scattering we revisit the problem of Coulomb phase. The usually used approximation of the momentum transfer squared (q 2) small compared to the inverse elastic slope is not justified within the kinematics of the E950 experiment. We go beyond this approximation and derive a new rather simple...
متن کاملInfrared divergence of the color-Coulomb self-energy in Coulomb gauge QCD
We investigate the spectrum of the Faddeev-Popov operator in Coulomb gauge QCD using quenched SU(3) lattice simulation. In the confinement phase, we observe the accumulation of the near-zero modes of the FP operator at large lattice volumes, and the color-Coulomb self-energy diverges in the infrared limit. Moreover, even in the deconfinement phase, the behavior of the FP eigenvalue density is q...
