Abstract
We study the SU(2) gauge theory with the interpolating gauge a la Parrinello-Jona-Lasinio-Zwanziger (PJLZ) with the gauge fixing functional F=\sum_{x\mu} \frac{1}{2}\mbox{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 λ at \lambda_c \sim 0.8.
