Non-linear realization of superconformal symmetry

Abstract

Within a framework of the non-linear realization, we investigate the transformation law and the effective lagrangian when superconformal symmetry is spontaneously broken down to super-Poincaré symmetry. We show that the determinant of the “supervierbein” provides an effective lagrangian which describes the interaction among the dilaton, the “axion” and the dilatino. We also briefly discuss the case in which the superconformal group is broken down to the Poincaré group.
