Analysis of the X(4350) as a scalar cc and Dₛ Dₛ mixing state with QCD sum rules

الأصل · EN

In this article, we assume that the narrow structure X(4350) is a scalar cc-Dₛ Dₛ mixing state, and study its mass using the QCD sum rules. The numerical result Mₓ=(4.37±0.15)GeV is in good agreement with the experimental data, the X(4350) may be a scalar cc-Dₛ Dₛ mixing state. Other possibility, such as a scalar (tensor) cscs tetraquark state is not excluded.
