  This is a report on our newly proposed model of dynamical supersymmetry
breaking with some details of the analysis involved. The model in the simplest
version has only a chiral superfield (multiplet), with a strong four-superfield
interaction in the K\"ahler potential that induces a real two-superfield
composite with vacuum condensate. The latter has supersymmetry breaking parts,
which we show to bear nontrivial solution following basically a standard
nonperturbative analysis for a Nambu--Jona-Lasinio type model on a superfield
setting. The real composite superfield has a spin one component but is
otherwise quite unconventional. We discuss also the parallel analysis for the
effective theory with the composite. Plausible vacuum solutions are illustrated
and analyzed. The supersymmetry breaking solutions have generated soft mass(es)
for the scalar avoiding the vanishing supertrace condition for the
squared-masses of the superfield components. We also present some analysis of
the resulted low energy effective theory with components of the composite
become dynamical. The determinant of the fermionic modes is shown to be zero
illustrating the presence of the expected Goldstino. The model gives the
possibility of constructing a supersymmetric standard model with all
(super)symmetry breaking masses generated dynamically and directly without the
necessity of complicated hidden or mediating sectors.
