In the first production run of the WASA experiment at COSY, the eta decay into three neutral pions was measured in proton-proton interactions at a proton beam kinetic energy of 1.4 GeV. The Dalitz plot of the three pions was studied using 1.2 × 105 fully reconstructed events, and the quadratic slope parameter α was determined to be - 0.027 ± 0.008 (stat) ± 0.005 (syst). The result is consistent with previous measurements and further corroborates the importance of pion-pion final state interactions.
