Description

We construct the s matrix for bound state (gauge-invariant) scattering for nonlinear sigma models defined on the manifold SU(N)/S(U(p)x (lower casex)U(n-p)) with fermions. It is not possible to compute gauge non-singlet matrix elements. In the present language they are not submitted to sufficiently many constraints derived from higher conservation laws. (author)

Abstract (Portuguese)

Constroi-se a matriz S para o estado ligado (invariante de gauge) de modelos sigma nao-lineares definidos na variedade SU(N)/S(U(p)x (lower cas x)U(n-p)) com fermions. Nao e possivel calcular elementos de matriz que nao sejam singletos de cor. Na presente liguagem esses objetos nao sao submetidos a vinculos suficientemente numerosos derivados de leis de conservacao superiores. (M.W.O.)
