Description

In this paper we present an analysis of the recent high-statistical KLOE data on the φ→ηπ0γ decay. This decay mainly goes through the a0γ intermediate state. The results obtained differ from those of previous fits: the data prefer a high a0 mass and a quite large a0 coupling to the KK-bar
