Abstract

We discuss the likely tetraquark interpretation of the X(1576) K+ K- isovector resonance recently reported by BES with JPC=1--. We point out that if this interpretation as a four-quark state is correct, the (s u sbar dbar) tetraquark decays might have striking signatures. We also provide predictions for possible analogous tetraquarks involving heavy quarks - (c q cbar qbar) and (b q bbar qbar).
