0 ( 2317 ) as a tetraquark state with QCD sum rules in heavy quark limit
نویسنده
چکیده
In this article, we take the point of view that the charmed scalar meson Ds0(2317) be a tetraquark state and devote to calculate its mass within the framework of the QCD sum rules approach in the heavy quark limit. The numerical values for the mass of the Ds0(2317) are consistent with the experimental data, there must be some tetraquark component in the scalar meson Ds0(2317). Detailed discussions about the threshold parameter and Borel parameter for the multiquark states are also presented. PACS number: 12.38.Aw, 12.38.Qk

متن کاملD s ( 2317 ) as a four - quark state in QCD sum rules
We perform a QCD sum rule study of the open-charmed Ds(2317) as a four-quark state. Using the diquark-antidiquark picture for the four-quark state, we consider four possible interpolating fields for Ds(2317), namely, scalar-scalar, pseudoscalar-pseudoscalar, vector-vector, and axialvector–axial-vector types. We test all four currents by constructing four separate sum rules. The sum rule with th...

We set up sum rules for heavy lambda decays in a full QCD calculation which in the heavy quark mass limit incorporates the symmetries of heavy quark effective theory. For the semileptonic decay of the Λ b we find at the zero recoil point a violation of the heavy quark symmetry of more than 20%. We test the method by calculating the decay width of the semileptonic Λ c decay and obtain a reasonab...
متن کاملSum Rules Calculation of Heavy Λ Semileptonic Decay
We set up sum rules for heavy lambda decays in a full QCD calculation which in the heavy quark mass limit incorporates the symmetries of heavy quark effective theory. For the semileptonic Λ c decay we obtain a reasonable agreement with experiment. For the Λ b semileptonic decay we find at the zero recoil point a violation of the heavy quark symmetry of about 20%.
