Phys. Rev. D 68, 011501(R) (2003) [3 pages]BABAR resonance as a new window of hadron physics
The possible decays of four-quark mesons are studied by assigning the newly observed BABAR resonance to a four-quark meson, FI+∼[cq][s̅ q̅ ] with q=u,d. It is expected that some of them can be observed as narrow resonances. The implication of the existence of four-quark mesons in hadronic weak interactions is also discussed. © 2003 The American Physical Society URL:
