In this talk we review, the quasiparticle description of the hot Yang-Mills theories, in which the quasiparticles propagate in (and interact with) a background field related to Z(N)-lines. We compare the present description with a more common one in which the effects of the Z(N)-lines are neglected. We show that it is possible to take into account the nonperturbative effects at the confinement transition temperature even without a divergent quasiparticle mass.

    In the context of the Quantum Cromodynamics, a low energy phenomena as it is the quark confinement cannot be described by the perturbation theory. In this paper, we consider the quark confinement for mesons through the exact spherical symmetric solutions of the movement equations of the SU(3)...

    A derivation of a zeroth-order Hamiltonian for use in multiconfigurational perturbation theories is presented. This derivation is based on a quasiparticle Green function formalism. It is shown that this formalism can naturally describe the physical picture of the zeroth-order Hamiltonian as an...

    We introduce a method that generates invariant functions from perturbative classical field theories depending on external parameters. By applying our methods to several field theories such as Abelian BF, Chern–Simons, and two-dimensional Yang–Mills theory, we obtain, respectively,...

    We consider the Yang-Mills flow on hyperbolic 3-space. The gauge connection is constructed from the frame-field and (not necessarily compatible) spin connection components. The fixed points of this flow include zero Yang-Mills curvature configurations, for which the spin connection has zero...

    Important information about the infrared dynamics of QCD is encoded in the behavior of its (of-shell) Green's functions, most notably the gluon and the ghost propagators. Due to recent improvements in the quality of lattice data and the truncation schemes employed for the Schwinger-Dyson...

    This work analyses a hypothetically improved perturbative approach taking a dressed massive-like gluon propagator and an effective coupling into account. As an early step, corrections were calculated to the ghost and gluon propagators, and the ghost-gluon vertex in the Landau gauge, pure SU(3)...

    The partition function of an oscillator disturbed by a set of electron particle paths has been computed by a path integral formalism which permits to evaluate at any temperature the relevant cumulant terms in the series expansion. The low temperature cutoffs in the anharmonic cumulant series are...

    Basing on a semiclassical picture of dyons, we present a nonperturbative model of a pure Yang-Mills theory at any temperatures, for an arbitrary simple gauge group. We argue that at low temperatures dyons drive the Yang-Mills system for all groups to a phase where the 'eigenphases' of the...

    We show that the non-Abelian magnetic monopole defined in a gauge-invariant way in SU(3) Yang-Mills theory gives a dominant contribution to confinement of the fundamental quark, in sharp contrast to the SU(2) case.
