Three body systems with strangeness and exotic systems
Abstract
We report on four 's and three 's, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave resonances found by solving the Faddeev equations in the coupled channel approach, which can be associated to the existing = -1, low lying baryon resonances. On the other hand we also report on a new, hidden strangeness state, mostly made of , with mass around 1920 MeV, which we think could be responsible for the peak seen in the around this energy. Finally we address a very novel topic in which we show how few body systems of several mesons can be produced, with their spins aligned up to J=6, and how these states found theoretically can be associated to several known mesons with spins J=2,3,4,5,6.
