Possible Interpretation of a New Resonance at 8.3 GeV

It is discussed whether the recently discovered resonance at 8.3 GeV can be interpreted as a weakly coupled fundamental pseudoscalar. Such a particle is readily incorporated in an SU(2) ⊗ U(1) gauge theory framework. The importance of mixing with ${\eta }_B$, ${\eta }_B^{\prime }$ for the phenomenology of such a particle is emphasized, and critical tests of their identification are proposed.
