LIGHT MESON SPECTROSCOPY WITH THE KLOE EXPERIMENT

摘要

In this paper we describe the status of the analyses in progress on light meson spectroscopy in the KLOE experiment. We present the analyses of φ decays into f_0(980)γ and a_0(980)γ, the Dalitz plot analysis of the η → π~+ π~- π~0 decay, the branching ratio measurement of η → π~0 γγ, the upper limits on Br(η → 3γ) and Br(η → π~+π~-), the measurement of the ratio Br(φ → η′γ)/Br(φ → ηγ) and φ leptonic width measurements.
