Viability of competing field theories for the driven lattice gas

It has recently been suggested that the driven lattice gas should be descri bed by an alternate held theory in the limit of infinite drive. We review t he original and the alternate field theory, invoking several well-documente d key features of the microscopics. Since the alternate field theory fails to reproduce these characteristics, we argue that it cannot serve as a viab le description of the driven lattice gas. Recent results, for the critical exponents associated with this theory, are reanalyzed and shown to be incor rect.
