Abstract

The possible decays of four-quark mesons are studied by assigning the newly observed BABAR resonance to a four-quark meson,

F_{I}^{+} \sim [cq] [\bar{s} \bar{q}]

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.
