摘要：
In this paper, we assume that there exists a pseudoscalar (D) over bar D-s(s0)( 2317) molecular state and study its mass with the molecule-type interpolating current in details using the QCD sum rules. The numerical result disfavors identifying the charmonium-like state Y (4274) as the (D) over bar D-s(s0)(2317) molecule.
