Studies of the $\ddot{I}‰$ meson with the KLOE detector

Abstract

The paper presents status of three studies involving the $\ddot{I}‰$ 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($\hat{I}¦\to \ddot{I}‰{\hat{I}}^3$) and the form factor measurement in the $\ddot{I}‰\to \ddot{I}{€}^0{l}^{+}{l}^{-}$ dalitz decay. The third study shows the effect $\ddot{I}{€}^0-\ddot{I}{€}^0$ interference has in the $\ddot{I}‰\to \ddot{I}{€}^{+}\ddot{I}{€}^{-}\ddot{I}{€}^0$ Dalitz plot when $\ddot{I}‰$ is produced through the $e^{+}{e}^{-}\to \ddot{I}‰\ddot{I}{€}^0$ channel.
