Nambu-Jona-Lasinio theory and dynamical breaking of supersymmetry

Abstract

A recently proposed new mechanism of D-term-triggered dynamical supersymmetry breaking is reviewed. Supersymmetry is dynamically broken by a nonvanishing D-term vacuum expectation value, which is realized as a nontrivial solution of the gap equation in the self-consistent approximation, as in the case of the Nambu-Jona-Lasinio model and BCS superconductivity.
