چکیده

We consider the monopole-antimonopole static potential in the confining phase of the Abelian Higgs model and in particular the corrections to the Coulomb-like potential at small distances r. By minimizing numerically the classical energy functional we observe a linear in r, stringy correction even at distances much smaller than the apparent physical scales. We argue that this term is a manifestation of the condition that the monopoles are connected by a mathematically thin line along which the scalar field vanishes. These short strings modify the operator product expansion as well. Implications for QCD are discussed.

We consider monopole-antimonopole static potential in the confining phase of the Abelian Higgs model and concentrate on the correction to the Coulomb-like potential at short distances r. By minimising numerically the classical energy functional we observe a linear in r correction so that a string-tension term survives even at distances much smaller than apparent physical scales. We argue that t...

Taking into account the terms ∼ m 2 in the effective chiral lagrangian , we show that, at θ = π, the theory with 2 light quarks of equal mass involves two degenerate vacuum states separated by a barrier. For N f = 3, the energy barrier between two vacua appears already in the leading order in mass. This corresponds to the first order phase transition at θ = π. The surface energy density of the ...

Gauged Wess-Zumino-Witten theory for compact groups is considered. It is shown that this theory has fermionic BRST-like symmetry and may be exactly solved using localization approach. As an example we calculate functional integral for the case of SU(2) group on the arbitrary Riemann surface. The answer is the particular case of Verlinde formula for the number of conformal blocks.
