Gauge Invariant SO(3)  Z2 Monopoles as Possible Source of Confinement in SU(2) Lattice Gauge Theory
Abstract
A gauge invariant procedure for extracting combined SO(3)Z2 monopoles in positiveplaquette SU(2) lattice gauge theory is shown. When these monopoles are eliminated through a constraint, the theory deconfines for all $\beta$ on $12^4$ and $20^4$ lattices even in the strong coupling limit, despite a rather strong average plaquette of around 0.64. This corresponds to an effective Wilson $\beta$ of 2.45, at which Wilsonaction lattices would be far into the confining region. This suggests that Wilsonaction confinement may be a strongcoupling lattice artifact; the continuum limit may not confine.
