Abstract

By studying the invariant-mass distribution of the e+e- in conversion decays, it is possible to learn more about mesons structure and underlying quark dynamics. At KLOE, the study of the ϕ → π0e+e- process is currently going to be finalized. At present, about 9000 events have been selected from a data sample of 1.7 fb-1 from 2004/2005 data taking campaign. A very good agreement between data and Monte Carlo distributions has been achieved for all interesting kinematical variables. A preliminary invariant-mass spectrum of e+e- is presented.
