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 * sD * 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.
