Nonlinear Realization of Spontaneously Broken N=1 Supersymmetry Revisited

Understand

This paper revisits the nonlinear realization of spontaneously broken N=1 supersymmetry.

• It is shown that the constrained superfield formalism can be reinterpreted in the language of standard realization of nonlinear supersymmetry via a new and simpler route.
• Explicit formulas of actions are presented for general renormalizable theories with or without gauge interactions.
• The nonlinear Wess-Zumino gauge is discussed and relations are pointed out for different definitions of gauge fields.
