  This paper aims to establish a connection between Pisarski's fixed point and
a (2+3)-spin-glass model with sextic confinement potential. This is made
possible by the unconventional power-counting induced by the effective kinetics
provided by the disorder coupling in the large $N$-limit. Because of the
absence of epsilon expansion, our approach is more attractive than the previous
one. It may be relevant to the signal detection issue in nearly continuous
spectra.
