摘要：

Assuming that the narrow state X(3872) is a molecule state consisting of primarily (DD*0)-D-0, we calculate its mass within the constituent quark model. The attractive potential between D-0 and D-*0 including one-sigma exchange and one-rho exchange is considered. We introduce the interaction between the heavy meson and light meson through the heavy meson form factor describing the heavy meson structure. The obtained mass of X is consistent with the experimental value. Adopting this method, we study the various molecule states with hidden bottom quark.
