Mass of X（3872） in Bethe-Salpeter Equation for Quarks

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 th...

Summary: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.
