STABILITY OF THE VACUUM AND DIELECTRIC MODEL OF CONFINEMENT IN QCD

    https://doi.org/10.1142/S0217732309030035Cited by:7 (Source: Crossref)

    After the gauge invariant gluon condensation, gluons remain as massless excitations. When the effective theory describing the condensation and the excitation is constructed, a constraint has to be imposed for the vacuum to be stable. The constraint implies the perfect dia-electricity and assures the solution of color flux tube when quarks are introduced. Thus the dia-electric model of Kogut–Susskind and 't Hooft is derived by the stability of the condensed vacuum.
