Strange hidden-charm pentaquarks with the meson exchange potential and coupling to the five-quark states

Yamaguchi, Yasuhiro   ; Hosaka, Atsushi; Takeuchi, Sachiko*; Takizawa, Makoto*

Recently, the exotic hadrons considered to be a pentaquark have been reported in the LHCb experiments. In this talk, we study the states as the hadronic molecule of a heavy meson and heavy baryon, where the pseudoscalar-meson exchange potential and the coupling to the compact five-quark states are introduced. We compute an energy and a decay width, and discuss a role of the interactions introduced.
