Monopole Loop Distribution and Confinement in SU(2) Lattice Gauge Theory

Abstract

The abelian-projected monopole loop distribution is extracted from maximal abelian gauge simulations. The number of loops of a given length falls as a power of the length nearly independent of lattice size. This power increases with $\beta=4/g^2$, reaching five around $\beta=2.85$, beyond which loops any finite fraction of the lattice size vanish in the infinite lattice limit, suggesting the continuum theory lacks confinement.Comment: 6 pages Latex, 4 eps figures.
