Analysis of the Y(4274) with QCD sum rules

Abstract

In this article, we assume that there exists a pseudoscalar $D_s{\bar{D}}_{s0}(2317)$ 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 $D_s{\bar{D}}_{s0}(2317)$ molecule.
