Unitarity in hadronic three-body decay and application to physics beyond the Standard Model


  • Mr. Mehmet Hakan AKDAG

Primary authors


We will discuss non-perturbative descriptions of three-body decays in hadronic systems and their application to parameterize physics beyond the Standard Model. First, we apply a novel implementation of three-body unitarity, based on a Bethe-Salpeter ansatz, to $\omega/\phi\to 3\pi$ and compare the results to the established dispersive framework of Khuri-Treiman equations on a quantitative level. With the latter, we analyze strong $C$- and CP-violation in hadronic $\eta^{(\prime)}$ decays
