Abstract
Assuming dynamical spontaneous breakdown of chiral symmetry for massless ga uge theory without scalar fields, we find a method to construct an effectiv e action of the dynamical Nambu-Goldstone bosons and elementary fermions by using auxiliary fields. Here dynamical particles are assumed to be compose d of elementary fermions. Various quantities including decay constants are calculated from this effective action.
