PJLZ--gauge fixing approach in SU(2) lattice gauge theory

Abstract

We study the SU(2) gauge theory with the interpolating gauge {\it a la} Parrinello--Jona-Lasinio--Zwanziger (PJLZ) with the gauge fixing functional $F=\sum_{xμ} {1/2}\tr (U_{xμ}σ_3U_{xμ}^{\dagger}σ_3)$. We find a strong indication of the non--analiticity with respect to the interpolating parameter $\lambda$ at ${\lambda }_c\sim 0.8$.
