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

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_{x\mu} {1/2}\tr (U_{x\mu}\sigma_3U_{x\mu}^{\dagger}\sigma_3). We find a strong indication of the non--analiticity with respect to the interpolating parameter
