Is Ds(2700) a charmed tetraquark state?

  • In this article, we assume that the Ds(2700) is a tetraquark state, which consists of a scalar diquark and a vector antidiquark, and calculate its mass with the QCD sum rules. The numerical result indicates that the mass of the vector charmed tetraquark state is about MV=(3.75±0.18) GeV or MV=(3.71±0.15) GeV from different sum rules, which is about 1 GeV larger than the experimental data. Such tetraquark omponent should be very small in the Ds(2700).

Abstract: 

In this article, we assume that the Ds(2700) is a tetraquark state, which consists of a scalar diquark and a vector antidiquark, and calculate its mass with the QCD sum rules. The numerical result indicates that the mass of the vector charmed tetraquark state is about MV=(3.75±0.18) GeV or MV=(3.71±0.15) GeV from different sum rules, which is about 1 GeV larger than the experimental data. Such tetraquark omponent should be very small in the Ds(2700).
