In this article, we assume that there exists a scalar D∗ s D̄∗ s molecular state in the J/ψφ invariant mass distribution, and study its mass using the QCD sum rules. The predictions depend heavily on the two criteria (pole dominance and convergence of the operator product expansion) of the QCD sum rules. The value of the mass is about MD∗ s D̄ s = (4.43± 0… CONTINUE READING
