✦ Synopsis

Decays of charmonium and charmed mesons provide a suitable environment in which to study the properties of light quark states. Using the approximately 25 million ψ(2S) decays collected with the CLEO-c detector at the Cornell Electron Storage Ring we present a precision measurement of the η mass and branching fractions and studies of spectroscopy in hadronic χ c decay. Additionally we use 572 pb -1 of data collected at the ψ(3770) to perform an analysis of the resonant substructure in the D + → K -π + π + decay channel.

In this paper we report KLOE results on scalar mesons f0,a0 using the last parametrization of the Kaon Loop model and a new global fit to the vector pseudoscalar photon transitions in order to obtain the gluonium content of the η meson and the pseudoscalar mixing angle φP . Both data from scalars an
