英文摘要: We present that including the hadron loop effects could help us to understand the spectrum of the heavier charmonium-like states and their strong decays simultaneously. By coupling the bare states to the opened thresholds, the pole positions which correspond to the observed states are shifted from the bare states predicted in the potential model to the complex energy plane. The pole masses are generally pulled down from the bare masses and the open-charm decay widths are related to the imaginary parts of the pole positions. Moreover, we also analyze the pole trajectory of chi(c1)(2P) state while the quark pair production rate from the vacuum varies in its uncertainty region, which indicates that the enigmatic (X)over bar(3872) state may be regarded as a state originating from the 1(++) c(c)over bar state by coupling to hadron loops as the others.
