Spin-parity analysis in the Dorren, Rittenberg and Yaffe model

Abstract

It is shown that the dual model given by Dorren, Rittenberg and Yaffe, similar to the dual Pokorski-Satz model, leads to the Gribov-Morrison rule for the parent states. In the Pokorski-Satz model this parity rule does not apply to the daughters. In the model considered by us the first daughter under A';,-trajectory satisfies the Gribov-Morrison rule.
