The investigation of η′ → ππη allows to study ππ and ηπ interactions and the possible influence of the scalar states f0(600) and a0(980) on the decay dynamics. 1.7 fb −1 of data taken with the KLOE detector at the DAΦNE e+e− collider have been analyzed with respect to the charged decay mode η′ → π+π−η. 7900 ± 90 event candidates have been extracted and can be used for a Dalitz plot analysis.
