TheX(4350) Narrow Structure Described As a 1{sup -+} Exotic State

We use the QCD sum rules to test if the narrow structure X(4350) can be described as a J{sup PC} = 1{sup -+} exotic D{sub s}*D{sub s0}* molecular state. We consider the contribution of the condensates up to dimension eight and we keep terms wich are linear in the strange quark mass m{sub s}. We obta...

Description
Summary:We use the QCD sum rules to test if the narrow structure X(4350) can be described as a J{sup PC} = 1{sup -+} exotic D{sub s}*D{sub s0}* molecular state. We consider the contribution of the condensates up to dimension eight and we keep terms wich are linear in the strange quark mass m{sub s}. We obtain m{sub D{sub sD{sub s{sub 0*}}} (5.05{+-}0.19) GeV which is much bigger than the X(4350) experimental mass.
