Abstract

We report on four Σ’s and three Λ’s, in the 1500–1800 MeV region, as two meson—one baryon S-wave (1/2)+ resonances found by solving the Faddeev equations in the coupled channel approach, which can be associated to the existing S = −1, J P = 1/2+ low lying baryon resonances. On the other hand we also report on a new, hidden strangeness N * state, mostly made of \({K \bar{K} N}\), with mass around 1920 MeV, which we think could be responsible for the peak seen in the γp → K + Λ around this energy. Finally we address a very novel topic in which we show how few body systems of several ρ 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.
