Within the dual superconductor model for the QCD vacuum we compare the field penetration depth λ with the correlation length ξ of the Higgs condensate. The comparison places the vacuum marginally on the type II side. A qualitative check of the interaction between two parallel flux tubes gives also consistent indications for a weak repulsive behaviour.

Abstract
Within the dual superconductor model for the QCD vacuum we compare the field penetration depth λ with the correlation length ξ of the Higgs condensate. The comparison places the vacuum marginally on the type II side. A qualitative check of the interaction between two parallel flux tubes gives also consistent indications for a weak repulsive behaviour.File in questo prodotto:
