Ground state admixture into the ψ″ (3.772)

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The usual potential model is used to estimate the orbital mixing into the ψ″ (3.772), whose leptonic width appears to be too small. It is emphasized that the admixedS-wave component is not saturated by the first radial excitation and contains a sizable part of the ground state.
