文摘From Bethe-Salpeter equation,we deduce the equation which describes the two-body system consisting of a scalar meson and a vector meson.This equation is applied to investigate the exotic narrow state X (3872) assumed as a molecule state composed of D 0 0.The contribution of the resonance 0 is the attractive interaction between two heavy mesons in this molecule state.The calculated mass of X is consistent with the experimental data.
