The Dalitz plot density is parametrised by a product of the P-wave phase space and a polynomial expansion in the normalised polar Dalitz plot variables Z and ϕ. For the first time, a deviation from pure P-wave phase space is observed with a significance of 4.1σ . The deviation is parametrised by a linear term 1+2αZ, with α determined to be +0.147±0.036, consistent with the expectations of ρ-meson-type final-state interactions of the P-wave pion pairs.}, cin = {IKP-1 / IKP-2 / ZEA-2 / IKP-4 / IKP-TA}, ddc = {530}, cid = {I:(DE-Juel1)IKP-1-20111104 / I:(DE-Juel1)IKP-2-20111104 / I:(DE-Juel1)ZEA-2-20090406 / I:(DE-Juel1)IKP-4-20111104 / I:(DE-Juel1)IKP-TA-20111104}, pnm = {612 - Cosmic Matter in the Laboratory (POF3-612)}, pid = {G:(DE-HGF)POF3-612}, experiment = {EXP:(DE-Juel1)WASA-at-COSY-20170712}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000404196500054}, doi = {10.1016/j.physletb.2017.03.050}, url = {https://juser.fz-juelich.de/record/830505}, }
