Tetra and pentaquarks from the molecular perspective

We present results for the analysis of the B + → J/ψϕK + which shows the contribution of two resonances, the X (4140) and X (4160) and a cusp at the $D_s^*\bar D_s^*$ threshold tied to the molecular character of the X (4160) resonance. In the second part we present the results for the theoretical ap...

Zusammenfassung:	We present results for the analysis of the B + → J/ψϕK + which shows the contribution of two resonances, the X (4140) and X (4160) and a cusp at the $D_s^\bar D_s^$ threshold tied to the molecular character of the X (4160) resonance. In the second part we present the results for the theoretical approach to the new Ω c states from the molecular perspective. In both cases we compare with results of the LHCb collaboration.
