Study of the heavy molecular states in the quark model with meson exchange interaction

Some charmonium-like resonances such as X（3872） can be interpreted as possible D （＊）  （＊） molecular states.Within the quark model,we study the structure of such molecular states and the similar B （＊）  （＊） molecular states by taking into account the light meson exchange （π,η,ρ,ω and σ） between two...

Summary:Some charmonium-like resonances such as X（3872） can be interpreted as possible D （＊）  （＊） molecular states.Within the quark model,we study the structure of such molecular states and the similar B （＊）  （＊） molecular states by taking into account the light meson exchange （π,η,ρ,ω and σ） between two light quarks from different mesons.
