Analysis of the ω and φ→ 3π Dalitz plot — •Franz Niecknig, Sebastian P. Schneider, and Bastian Kubis — Helmholtz-Institut für Strahlen- und Kernphysik (Theorie), Nussallee 14-16, D-53115 Bonn

The theoretical description of vector meson interactions in hadron physics remains a challenge. With the ongoing experimental interest in ω→3π and φ→3π decays the need for equally precise theoretical predictions remains. The prevailing treatments all lack a thorough inclusion of final state interactions.

In this talk we will introduce a dispersive approach to these decays and study how crossed-channel rescattering effects shape the Dalitz plot.
