Description
The X(3872) is investigated by employing the quark-hadron hybrid model, that consists of the cc¯ core, D(∗)D¯∗, J/ψω, and J/ψρ two-meson states. Due to the attraction from the cc¯-DD¯∗ coupling and from the OPEP tensor coupling, a very thin peak can appear at the D0D¯∗0 threshold. The energy of the corresponding pole of the scattering matrix is E=+0.06−0.14i MeV, which is on the physical sheet and above the threshold, the same as the one of the poles from the LHCb data analysis.
