On the Nonlinear Realization of the Superconformal Symmetry
Hiroshi Kunitomo
Abstract
The nonlinear realization of the superconformal symmetry in two dimensions is considered. The superconformal symmetry is realized by means of dimension -1/2\ Nambu-Goldstone fermion ξ\ and its dimension 3/2 conjugate η. A matter coupling of these Nambu- Goldstone fermions reproduce the realization found by Berkovits and Vafa to show the equivalence between the bosonic string and a N=1\ superstring. This indicates that this equivalence is a result of the super Higgs mechanism as a two dimensional field theory, in which the NG fermions become unphysical.
