We have studied, with the KLOE detector at the DAΦNE Φ-Factory, the dynamics of the decay η Ï+Ï-Ï0using η mesons from the decay Ï Î·Î³ for an integrated luminosity = 450 pb-1.

Abstract
We have studied, with the KLOE detector at the DAΦNE Φ-Factory, the dynamics of the decay η Ï+Ï-Ï0using η mesons from the decay Ï Î·Î³ for an integrated luminosity = 450 pb-1. From a fit to the Dalitz plot density distribution we obtain a precise measurement of the slope parameters. An alternative parametrization relates the Ï+Ï-Ï0slopes to that for η 3Ï0showing the consistency of KLOE results for both channels. We also obtain the best confirmation of the C-invariance in the η Ï+Ï-Ï0decay.File in questo prodotto:
