Abstract
We present a measurement of the slope parameter α for the ηâ3Ï0 decay, with the KLOE experiment at the DAΦNE Ï-factory, based on a background free sample of â¼17 million η mesons produced in Ï radiative decays. By fitting the event density in the Dalitz plot we determine α=â0.0301±0.0035statâ0.0035+0.0022syst. The result is in agreement with recent measurements from hadro- and photo-production experiments.
