Abstract

We present a measurement of the slope parameter a for the eta -> 3 pi(0) decay with the KLOE experiment at the DA Phi NE phi-factory based on a background free sample of similar to 17 million eta mesons produced in phi radiative decays By fitting the event density in the Dalitz plot we determine alpha = -0 0301 +/- 0 0035stat(-0 0035)(+0 0022) syst The result is in agreement with recent measurements from hadro- and photo-production experiments (C) 2010 Elsevier BV All rights reserved
