摘要：
We use the QCD sum rules to analize the hadronic decay D-sJ(+)(2317) -> D(s)(+)pi(0), in the hypothesis that the D-sJ(+)(2317) can be identified as a four-quark state. We use a diquark-antidiquark current and work to the order of ins in full QCD, without relying on I Inic expansion. We find that the partial decay width of the hadronic isospin violating mode is proportional to the isovector quark condensate, < 0 vertical bar(d) over bard - (u) over baru vertical bar 0 >. The estimated partial decay width is of the order of 6 keV. (c) 2006 Elsevier B.V. All rights reserved.
