Abstract: In this talk, we will briefly introduce our work on Vub extraction, where a model-independent dispersion theory is proposed. In the second part, we will show our recent progress on the exotic XYZ states, where the definition of compositeness for resonance is quantified. Using a more general two-body scattering amplitude we find several new points for X(3872) that has not been realized in our community.
