Structure of S/emph> from nuclear production experiments

Abstract

The three models for the structure of S*, where it is considered as a member of the qq L=1 nonet, or as a member of the lightest q2q 2 nonet or as a KK molecule, can be distinguished by studying the A dependence of the production cross sections at high energies of the inclusive reaction +AS*+X and of the exclusive reaction +AS*+N+(A-1). The energy dependence of the inclusive cross section can provide an independent test for the KK molecular model where we find a depletion in the cross section at energies corresponding to the Y* resonances of the K-nucleon system. © 1987 The American Physical Society.
