Abstract

The paper presents status of three studies involving the $\omega$ meson using data collected by the KLOE detector. The first two projects are feasibility studies performed on simulated data concerning an upper limit measure ment of BR($\Phi \to \omega \gamma$) and the form factor measurement in the $\omega\to\pi^0l^+l^-$ dalitz decay. The third study shows the effect $\pi^0 - \pi^0$ interference has in the $\omega\to\pi^+\pi^-\pi^0$ Dalitz plot when $\omega$ is produced through the $e^+e^-\to\omega\pi^0$ channel.
