Abstract Using the cumulant expansion for an averaged Wilson loop we derive an action of the gluodynamics string in the form of a series in powers of the correlation length of the vacuum. In the lowest orders it contains the Nambu-Goto term and the rigidity term with corresponding coupling constants computed from the bilocal correlator of gluonic fields. 

CURVATURE EXPANSION FOR THE GLUODYNAMICS STRING INCLUDING PERTURBATIVE GLUONIC CONTRIBUTIONS

Perturbation theory, which represents a Wilson loop in the SU(2) gluodynamics as an integral over all the orientations in color space, in the nonperturbative QCD vacuum and the non-Abelian Stokes

String Representation of Gauge Theories

In this talk, various approaches to the problem of evaluation of the field strength correlators in the SU(3)-gluodynamics, which play the major role in the Stochastic Vacuum Model, are reviewed. This

Towards the String representation of the dual Abelian Higgs model beyond the London limit

We perform a path-integral analysis of the string representation of the dual abelian Higgs (DAH) model beyond the London limit, where the string describing the vortex of a flux tube has a finite

String breaking in QCD: dual superconductor vs. stochastic vacuum model

Effects of dispersion of the chromoelectric field of the flux tube on the string-breaking distance are studied. The leading-order correction is shown to slightly diminish the result following from

Ensemble of Vortex Loops in the Abelian-Projected SU(3)-Gluodynamics

Grand canonical ensemble of small vortex loops emerging in the London limit of the effective Abelian-projected theory of the SU(3)-gluodynamics is investigated in the dilute gas approximation. An

SU(N) confining strings

String representation of the SU(N)-version of compact QED in three dimensions is constructed. It is demonstrated how the resulting SU(N)-generalization of the so-called theory of confining strings

SU(N) fundamental and adjoint confining strings

String representations of the Wilson loop are constructed in the SU(N)-version of compact QED in three and four dimensions. This is done exactly in the case of the fundamental Wilson loop and in the

The theory of quantum Abrikosov-Nielsen-Olesen strings is constructed and it is shown that in four space-time dimensions in the limit of infinitely thin strings, the conformal anomaly is absent, and the quantum theory exists.

Using completely fixed axial-like gauges, I construct the unique inversion A (F) for the potential A in terms of the field strength F. A change of variable to F results in a field-strength
