Hadronic three-body decays of light vector mesons

Regular Article - Theoretical Physics

Abstract

The decays of light vector mesons into three pseudoscalar mesons are calculated to leading order in the recently proposed counting scheme that is based on the hadrogenesis conjecture. Fully differential as well as integrated decay widths are presented. Since the required parameters have been fixed by other processes, the considered three-body decays are predictions of the presented approach. The decay width of the omega meson into three pions agrees very well with the experiment. The partial decay widths of the K* into its three K \( \pi\) \( \pi\) channels are predicted.
