Abstract:

We investigate the hidden-charm pentaquarks as D*Λc and D*Σ*c molecules coupled to the compact five-quark states. The coupling to the five-quark states is treated as the short range potential, where the relative strength for the meson-baryon channels is determined by the structure of the five-quark states. Introducing the five-quark state potential and the one pion exchange potential, the coupled-channel Schrodinger equations are solved. We found that resonant and bound states appear, where the five-quark state potential plays an important role to produce these states. We also report the results in the hidden-bottom sector.
