A new tetra-quark interpretation of X(3872)

Abstract

A new tetra-quark interpretation of X(3872) is presented. In this model, X(3872) consists of two degenerate tetra-quark mesons, [cn](cbar nbar) +- (cn)[cbar nbar]I=0, and, therefore, it is naturally understood that X(3872) decays into two different eigenstates of G-parity.
