The Λp interaction close to the ΣN threshold is considered. Specifically, the pronounced structure seen in production reactions like K − d → π − Λp and pp → K + Λp around the ΣN threshold is analyzed. Modern interaction models of the coupled ΛN −ΣN systems generate such a structure either due to the presence of a (deuteron-like) unstable bound state or of an inelastic virtual state. A determination of the position of the prominent peak as observed in various experiments for the two aforementioned reactions leads to values that agree quite well with each other. Furthermore, the deduced mean value of 2128.7 ± 0.3 MeV for the peak position coincides practically with the threshold energy of the Σ + n channel. This supports the interpretation of the structure as a genuine cusp, signaling an inelastic virtual state in the 3 S1 − 3 D1 partial wave of the ΣN isospin 1/2 channel. There is also evidence for a second peak (or shoulder) in the data sets considered which appears at roughly 10-15 MeV above the ΣN 1 threshold. However, its concrete position varies significantly from data set to data set and, thus, a theoretical interpretation is difficult.

In this talk we review results from studies with unconventional many hadron systems containing mesons: systems with two mesons and one baryon, three mesons, some novel systems with two baryons and one meson, and finally systems with many vector mesons, up to six, with their spins aligned forming states of increasing spin. We show that in many cases one has experimental counterparts for the states found, while in some other cases they remain as predictions, which we suggest to be searched in BESIII, Belle, LHCb, FAIR and other facilities.

“…This method is especially suitable to study the system in which two of the three particles are bound forming a cluster and this cluster is not much altered by the collision of the third particle [8][9][10]. This method has proved to be rather reliable for cases like K-deuteron scattering very close to threshold [11,12]. In recent years the FCA to Faddeev equations has been successfully applied to the study of many three body interactions.…”

We study the interaction of the a ρ and D * ,D * with spins aligned using the Fixed Center Approximation to the Faddeev equations. We select a cluster of D * D * , which is found to be bound in I = 0 and can be associated to the X(3915), and let the ρ meson orbit around the D * andD * . In this case we find an I = 1 state with mass around 4340 MeV and narrow width of about 50 MeV. We also investigate the case with a cluster of ρD * and let theD * orbit around the system of the two states. The ρD * cluster is also found to bind and leads to the D * 2 (2460) state. The addition of the extraD * produces further binding and we find, with admitted uncertainties, a state of I = 0 around 4000 MeV, and a less bound narrow state with I = 1 around 4200 MeV.
