Monopole in the Dilatonic Gauge Field Theory

M ay 2 00 0 Monopole in the Dilatonic Gauge Field Theory

A numerical study of coupled to the dilaton field, static, spherically symmetric monopole solutions inspired by the Kaluza-Klein theory with large extra dimensions are presented. The generalized Prasad-Sommerfield solution is obtained. We show that monopole may have also the dilaton cloud configurations.

The monopole mass in the random percolation gauge theory

We study the behaviour of the monopole at finite temperature in the (2 + 1)-dimensional lattice gauge theory dual to the percolation model; by exploiting the correspondences to statistical systems , we possess powerful tools to evaluate the monopole mass both above and below the critical temperature with high-precision Monte Carlo simulations.

Monopole Order Parameter in Su (2) Lattice Gauge Theory *

We present the results of the numerical calculation of the probability distribution of the value of the monopole creation operator in SU (2) lattice gluodynamics. We work in the maximal abelian projection. It occurs that at the low temperature, below the deconfinement phase transition the maximum of the distribution is shifted from zero, which means that the effective constraint potential is of...

Vortex Structure vs. Monopole Dominance in Abelian-Projected Gauge Theory

We find that Polyakov lines, computed in abelian-projected SU(2) lattice gauge theory in the confined phase, have finite expectation values for lines corresponding to two units of the abelian electric charge. This means that the abelian-projected lattice has at most Z2, rather than U(1), global symmetry. We also find a severe breakdown of the monopole dominance approximation, as well as positiv...
