Lefton-righton formulation of massless Thirring models

Abstract

Completely bosonized actions which possess classical Siegel symmetries and which contain interactions between purely lefton currents with purely righton currents are presented. It is argued that these actions correspond to the complete bosonization, at the level of lagrangians, of massless fermionic Thirring models. Both abelian and non-abelian cases are considered. Partial results for the (1,0) supersymmetric extensions of these lagrangians are obtained. The role of these bosonized Thirring models in the coupling of a complete massless spectrum of background fields to compactified string theories is illustrated.
