摘要：

Quantum corrections for affine Toda theories based on the nonsimply laced Lie algebras a(2n-1)(2) and C(N)(1) distort the classical mass spectrum. We show that at the one-loop level fermionic generalizations based on the Lie superalgebras A(2)(0,2n - 1) and C(2)(n + 1) lead to corrections that preserve the classical spectrum. Thus, these generalizations may retain the integrability properties and exact S-matrices which in the purely bosonic theories seem to be destroyed by quantum effects.
