The decay constant of [Formula: see text] is the key quantity to determine the production rate of [Formula: see text] in τ decays. By assuming [Formula: see text] is the lowest scalar bound state of [Formula: see text], the decay constant can be calculated reliably in QCD sum rule. Then the decay branching ratio of [Formula: see text] is predicted to be about (7.9±3.1)×10-5. If this branching ratio can be measured by experiment, it should be helpful to make clear the structure of [Formula: see text].
