Some Developments in Light Quark Spectroscopy

Among the many unresolved questions in light quark spectroscopy, the underlying structure of the scalar mesons and the identification of states with a gluonic content rank high. Recently, new information has come from $ϕ$ radiative decays, $J/ψ$, $τ$, $D$ and $D_s$ meson decays. Other papers in this conference review radiative transitions of $ϕ$ and $J/ψ$. This paper discusses new information on the scalar sector primarily that from decays of $D$ and $D_s$ mesons.
