Query: BABAR resonance as a new window of hadron physics   Possible decays of four-quark mesons are studied by assigning the newly
observed BABAR resonance to a four-quark meson with C=S=I=1. It is expected
that some of them can be observed as narrow resonances. Implication of
existence of four-quark mesons in hadronic weak interactions is also discussed.
