摘要

En 中文

In this talk, I discuss our recent studies of three-hadron systems and the resonances found therein The studies consist of solving Faddeev equations with the input two body interactions obtained from the chiral Lagrangians The systems which we study are either made of two mesons and a baryon or of three mesons The motivation for these studies comes from the data on many baryon resonances, especially the ones with J(pi) = 1/2(+), which show a large branching ratio to the two meson-one baryon decay channels. In addition to tins, several new studies at BES, BELLE, BABAR etc., claim the existence of new meson resonances which seem to couple strongly to three-meson systems, where mostly two out of the three mesons appear as a known resonance Hitherto, we have studied two meson-one baryon systems with strangeness = 1, 0 and 1 and three-meson systems made of two-pseudoscalars and a vector meson As we will show in this manuscript, we find many resonances which couple to three-hadrons.
