Rescattering effects in eta {\to} 3pi decays
Sebastian P. Schneider, Bastian Kubis, Christoph Ditsche
The isospin-breaking decay eta {\to} 3pi is an ideal tool to extract information on light quark mass ratios from experiment. For a precise determination, however, a detailed descri…

The cusp effect in eta' --> eta pi pi decays
Bastian Kubis, Sebastian P. Schneider
Strong final-state interactions create a pronounced cusp in eta' --> eta pi0 pi0 decays. We adapt and generalize the non-relativistic effective field theory framework developed for…
