説明

We investigate the nonlinear realization of spontaneously broken N=2 superconformal symmetry in 4 dimensions. We study Nambu-Goldstone degrees of freedom for the partial breaking of N=2 superconformal symmetry down to N=1 super-Poincare symmetry, where we get the chiral NG multiplet of dilaton and the vector NG multiplet of NG fermion of broken Q-supersymmetry. Evaluating the covariant derivatives and supervielbeins for the chiral as well as the full superspace, we obtain the nonlinear effective lagrangians [1].
