چکیده
We present the results of a study of the free energy of a monopole pair in pure SU(2) theory at finite temperature , both below and above the deconfinement transition. We find a Yukawa potential between monopoles in both phases. At low temperature, the screening mass is compatible with the lightest glueball mass. At high temperature, we observe an increased screening mass with no apparent discontinuity at the phase transition.

We found a quantum perfect lattice action in the 4-dimensional monopole current theory which is known as an effective theory in the infrared region of QCD. The perfect monopole action is transformed exactly into a lattice action of a string model. When the monopole interactions are weak as in the case of infrared SU(2) QCD, the string interactions are strong. The static potential and the string...

We present an exact local bosonic algorithm for the simulation of dynamical fermions in lattice QCD. We show that this algorithm is a viable alternative to the Hybrid Monte Carlo algorithm.

We study color confinement properties of the multi-instanton system, which seems to carry an essence of the nonperturbative QCD vacuum. Here we assume that the multi-instanton system is characterized by the infrared suppression of instantons as f (ρ) ∼ ρ −5 for large size ρ. We first investigate a monopole-clustering appearing in the maximally abelian (MA) gauge by considering the correspondenc...

We study the relation between center vortices and instantons in lattice QCD. One approach to understanding the physical origin of confinement and chiral symmetry breaking is to attempt to capture the essential physics in a much smaller number of degrees of freedom by projecting from a maximal abelian or maximal center gauge. For simplicity, we consider SU (2) and denote a link variable transfor...

Scenario according to which the SU(2)-gluodynamics is a theory with a nontrivial fixed point is analyzed from the point of view of the modern Monte-Carlo (MC) lattice data. It is found that an assumption of the first order fixed point g = g f of the beta function β f (g) has no contradictions with existing MC lattice data. The beta function parameters are found from the requirement of constant ...
