Supersymmetric Nonlinear Sigma Models as Gauge Theories
Supersymmetric Nonlinear Sigma Models as Gauge Theories
Supersymmetric nonlinear sigma models are obtained from linear sigma models by imposing supersymmetric constraints. If we introduce auxiliary chiral and vector superfields, these constraints can be expressed by D-terms and F-terms depending on the target manifolds. Auxiliary vector superfields appear as gauge fields without kinetic terms. If there are no …
