It is found that the Dalitz plot distribution differs from the pure P-wave phase space with a statistical significance of 18.9 sigma. The parameters from the fit to data are in reasonable agreement with those without the cross-channel effect within the dispersive framework, which indicates that the cross-channel effect in omega -> pi(+) pi(-) pi(0) is not significant.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8505944850010.1103/PhysRevD.98.112007Q1WOS:000454167100001
