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

The recently observed X(3872) resonance, which is difficult to assign a conventional cc charmonium state in the quark model, may be interpreted as a molecular state. Such a molecular state is a hidden flavor four quark state because of its charmonium-like quantum numbers. The s-channel one gluon exchange is an interaction which only acts in the hidden flavor multi-quark system. In this paper, we will study the X(3872) and other similiar hidden flavor molecular states in a quark model by taking into account the s-channel one gluon exchange interaction. 相似文献
