TL;DR

This paper analyzes gaugino condensation in supersymmetric gauge theories using a linear multiplet, demonstrating duality with chiral superfields and implications for superstring nonperturbative effects.

Contribution

It introduces a real vector superfield to describe gauge invariants and shows duality with chiral superfields persists nonperturbatively.

Findings

Duality between linear and chiral multiplet formulations is maintained.

The effective Lagrangian approach captures nonperturbative effects.

Supports the relevance of chiral-linear duality in superstring theory.

Abstract

An effective lagrangian analysis of gaugino condensation is performed in a supersymmetric gauge theory with field-dependent gauge couplings described with a linear multiplet. An original aspect of this effective lagrangian is the use of a real vector superfield to describe composite gauge invariant degrees of freedom. The duality equivalence of this approach with the more familiar formulation using a chiral superfield is demonstrated. These results strongly suggest that chiral-linear duality survives nonperturbative effects in superstrings.
