Abstract
We investigate the effect of an external gravitational fields to the c hiral symmetry breaking in the supersymmetric (SUSY) Nambu-Jona-Lasini o (NJL) model coupled to gravity in a non-supersymmetric way. Evaluati ng the effective potential in the leading order of the 1/N-c-expansion and in the linear curvature approximation, it is possible to have the chiral symmetry breaking in the SUSY NJL model in an external gravita tional fields. In the broken phase the dynamically generated mass is a nalytically and numerically calculated.
