We introduce a simple model of dynamical supersymmetry breaking. It is like asupersymmetric version of a Nambu--Jona-Lasinio model with a spin onecomposite. The simplest version of the model as presented here has a singlechiral superfield (multiplet) with a four-superfield interaction. The latterhas the structure of the square of the superfield magnitude square. A vacuumcondensate of the latter is illustrated to develop giving rise to supersymmetrybreaking with a soft mass term for the superfield. We report also the effectivetheory picture with a real superfield composite, illustrating the matchingeffective potential analysis and the vacuum solution conditions for thecomponents. The nature of its fermionic part as the Goldstone mode ispresented. Phenomenological application to the supersymmetric standard model isplausible.
