AbstractUsing the soft-pion theorem and the assumption on the final-state interactions, we include the contribution of the DK continuum into the QCD sum rules for the D-sJ(2317) meson. We find that this contribution can significantly lower the mass and the decay constant of the D-s(0(+)) state. For the value of the current quark mass m(c)(m(c)) = 1.286 GeV, we obtain the mass of D-s(0(+)) M=2.33 +/- 0.02 GeV in the interval s(0) = 7.5-8.0 GeV2, being in agreement with the experimental data, and the vector current decay constant of D-s(0(+)) f(0)=0.128 +/- 0.013 GeV, much lower than those obtained in the previous literature.
