Measurement of the slope parameter αfor the η\to 3π^0 decay at KLOE

KLOE collaboration, F. Ambrosino, A. Antonelli +80

We report a preliminary measurement of the slope parameter $\alpha$ for the $η\to 3\piz$ decay carried out with KLOE at DA$\Phi$NE; where $\alpha$ is the parameter describing the energy depende…
