Hamiltonian approach to QCD in Coulomb gauge at zero and finite temperature

Blog Article

I report on recent results obtained within the Hamiltonian approach to QCD in Coulomb gauge.By relating the Gribov confinement scenario to the center vortex poise pads in bulk picture of confinement it is shown that the Coulomb string tension is tied to the spatial string tension.For the quark sector a vacuum wave functional is used which results in variational equations which are arrethe bush balm free of ultraviolet divergences.

The variational approach is extended to finite temperatures by compactifying a spatial dimension.For the chiral and deconfinement phase transition pseudo-critical temperatures of 170MeV and 198 MeV, respectively, are obtained.
