Where have all the Pseudoscalar Glueballs Gone?

Part of the Progress in Physics book series (PMP, volume 8)


We review the experimental and theoretical status of the ζ (1440) observed in ψ → γX. We comment on previous mass matrix studies and present our own mixing scheme, which can accommodate ζ (1440) either as a radial excitation or as a glueball. To distinguish between the two rates, more data and analysis are needed. In particular, it would be useful to know the spin-parity of the broad object seen at 1710 MeV In ψ → γX.
