Title: Dual superconductivity and typology of the QCD vacuum

Abstract

Within the dual superconductor model for the QCD vacuum we compare the field penetration depth {lambda} with the correlation length {xi} 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.

  • The Q{bar Q} semirelativistic interaction in QCD can be simply expressed in terms of the Wilson loop and its functional derivatives. In this approach we present the Q{bar Q} potential up to order 1/m{sup 2} using the expressions for the Wilson loop given by the Wilson minimal area law (MAL), the stochastic vacuum model (SVM), and dual QCD (DQCD). We confirm the original results given in the different frameworks and obtain new contributions. In particular we calculate up to order 1/m{sup 2} the complete velocity-dependent potential in the SVM. This allows us to show that the MAL model is entirelymore » contained in the SVM. We compare and discuss also the SVM and the DQCD potentials. It turns out that in these two very different models the spin-orbit potentials show up the same leading nonperturbative contributions and 1/r corrections in the long-range limit. {copyright} {ital 1997} {ital The American Physical Society}« less
  • We show that in a sufficiently strong magnetic field the QCD vacuum may undergo a transition to a new phase where charged {rho}{sup {+-}}mesons are condensed. In this phase the vacuum behaves as an anisotropic inhomogeneous superconductor which supports superconductivity along the axis of the magnetic field. In the directions transverse to the magnetic field the superconductivity is absent. The magnetic-field-induced anisotropic superconductivity - which is realized in the cold vacuum, i.e. at zero temperature and density - is a consequence of a nonminimal coupling of the {rho} mesons to the electromagnetic field. The onset of the superconductivity of themore » charged {rho}{sup {+-}}mesons should also induce an inhomogeneous superfluidity of the neutral {rho}{sup 0} mesons. We also argue that due to simple kinematical reasons a strong enough magnetic field makes the lifetime of the {rho} mesons longer by closing the main channels of the strong decays of the {rho} mesons into charged pions.« less
  • We investigate the dual superconductivity hypothesis in pure SU(2) lattice gauge theory. We focus on the dual Meissner effect by analyzing the distribution of the color fields due to a static quark-antiquark pair. We find evidence of the dual Meissner effect both in the maximally Abelian gauge and without gauge fixing. We measure the London penetration length. Our results suggest that the London penetration length is a physical gauge-invariant quantity. We put out a simple relation between the penetration length and the square root of the string tension. We find that our estimation is quite close to the extrapolated continuummore » limit available in the literature. A remarkable consequence of our study is that an effective Abelian theory can account for the long range properties of the SU(2) confining vacuum.« less
  • A scaling analysis is made of the order parameter describing monopole condensation at the deconfining transition of N{sub f}=2 QCD around the chiral point. In accordance with scaling properties of the specific heat, studied in a previous paper, scaling is consistent with a first order transition. The status of dual superconductivity of the vacuum as a mechanism of color confinement is reviewed.
  • We discuss the vacuum structure of QCD with two flavors of Wilson fermions. We derive two possible scenarios: (i) If the spectral density {rho}{sub U}({lambda},{kappa}) of the overlap Hamiltonian in a fixed background gauge field is not symmetric in {lambda}, Hermiticity is violated and Hermiticity violation effects could influence numerical determinations of the {eta} meson mass if we are not near enough to the continuum limit, where Hermiticity should be recovered; (ii) otherwise we argue that, under certain assumptions, new phases appear beside the Aoki phase, which can be characterized by a nonvanishing vacuum expectation value of i{psi}{sub u}{gamma}{sub 5}{psi}{submore » u}+i{psi}{sub d}{gamma}{sub 5}{psi}{sub d}, and with vacuum states that cannot be connected with the Aoki vacua by parity-flavor symmetry transformations. Quenched numerical simulations suggest that the second scenario is more likely realized.« less
