Using the FOCUS spectrometer (experiments 687 and 831 at Fermilab) we confirm the existence of a diffractively photoproduced enhancement in K + K -at 1750 MeV/c 2 with nearly 100 times the statistics of previous experiments. We also observe a narrow dip structure at 1.9 GeV/c 2 in a study of diffractive photoproduction of the 3Ο + 3Ο -final state.
In this paper we present results on the spectroscopy of high-energy light meson photoproduction from the FOCUS (E831) and E687 experiments at Fermilab. Although both experiments were focused on charm physics, a very large sample of diffractively photoproduced light-

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 Ο(2S) decays collected with the CLEO-c detector at the Cornell Electron Storage Ring we present a precision measurement of the Ξ· mass and
## Interpretation of the D-meson decay-dynamics has revealed itself to be strongly dependent on our understanding of the light-meson sector. The statistics collected by FOCUS is already at a level that manifests parametrization problems for scalar particles. In this paper the first application of
