Constituent counting rule and the production of at high energies *

Abstract

Abstract The constituent counting rule, determining the scaling behavior of the transition amplitudes in an exclusive process at high energies, is applied to probe the internal structure of the newly observed resonance. Several selected exclusive processes at high energies for the production of are discussed. Results of two structural scenarios for , a hexaquark dominant compact system in the quark degrees of freedom, and a three-body bound state in the hadronic degrees of freedom, are analyzed and compared. A rather remarkable difference between the results of these two scenarios for the mentioned processes are addressed.
