Abstract

The X(3872) is investigated by employing the quark-hadron hybrid model, that consists of the \(c\bar{c}\) core, \(D^{(*)}\bar{D}{}^*\), \(J/\psi \omega \), and \(J/\psi \rho \) two-meson states. Due to the attraction from the \(c\bar{c}\)-\(D\bar{D}{}^*\) coupling and from the OPEP tensor coupling, a very thin peak can appear at the \(D^{0}\bar{D}{}^{*0}\) 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.
