摘要
A new tetra-quark interpretation of X(3872) is presented. In this model, X(3872) consists of two degenerate tetra-quark mesons similar to {[cn]((c) over bar(n) over bar) +/- (cn)[(c) over bar(n) over bar]} I=0, and, therefore, it is naturally understood that X(3872) decays into two different eigenstates of G parity.
