GAUGINO CONDENSATES AND CHIRAL-LINEAR DUALITY - AN EFFECTIVE LAGRANGIAN ANALYSIS

We show how to formulate the phenomenon of gaugino condensation in a s uper-Yang-Mills theory with a field-dependent gauge coupling described with a linear multiplet. We prove the duality equivalence of this app roach with the more familiar formulation using a chiral superfield. In so doing, we resolve a longstanding puzzle as to how a linear-multipl et formulation can be consistent with the dynamical breaking of the Pe ccei-Quinn symmetry which is thought to occur once the gauginos conden se. In our approach, the composite gauge degrees of freedom are descri bed by a real vector superfield, V, rather than the chiral superfield that is obtained in the traditional dual formulation. Our dualization, when applied to the case of several condensing gauge groups, provides strong evidence that this duality survives strong-coupling effects in string theory.
