Hyperon non-leptonic decays in χPT, revisited
2022.11.16 13:05 - Katarzyna KuźniarThough weak non-leptonic decays of hyperons - strange baryons - have been investigated before, an update is urgently needed in view of recent significant measurements from the BESIII collaboration. Only with such an update, future high-precision data of weak non-leptonic decays can be properly interpreted. Such hadronic decays are characterized by two distinct contributions to the decay amplitude, called S- and P-wave.
