D. Gong et Jm. Liu, VARIATIONAL STUDY OF 3-DIMENSIONAL SU(3) LATTICE GAUGE-THEORY WITH INDEPENDENT PLAQUETTE TRIAL ACTION, Communications in Theoretical Physics, 19(2), 1993, pp. 225-230
The phase structure of 3-dimensional SU(3) lattice gauge theory is stu
died by using the variational method with an independent plaquette tri
al action. The mean plaquette internal energy E(p) approximately beta
curve is smooth, which shows only one confining phase, and is better t
han that given by the independent link trial action.
