Investigation of molecular states with charm and beauty hadrons

Abstract

In our work, we have made some investigations on the hadronic spectrum, mostly in the heavy quark sector, focusing mainly on the baryonic states with charm and beauty. Besides, we also did some works on the mesonic states both in the light and the heavy quark sectors. First, we explore the recently developed three-body interaction formalism, the fix center approximation to the Faddeev equations, to study some strong interaction of the three-body hadronic systems. Second, we investigate the two-body interactions in the charm and beauty sector with the coupled channel approach, by taking into account the constraints of heavy quark spin symmetry. Third, we study the decay models and properties of some resonances, theoretically predicted in the strong interactions of low energy QCD.
