✦ Synopsis

Three-dimensional supersymmetric generalized non-linear sigma models are shown to exhibit second-order phase transition due to spontaneous breakdown of the internal symmetry below a critical value of the coupling constant. Supersymmetry remains unbroken in both phases. Supergraph diagram technique of the corresponding 1IN expansion and the particle spectrum are derived.
