Investigating the Tetraquark Structure of the New Mesons

چکیده
Using the QCD sum rule approach we investigate the vertex associated with the decay D0(0+) → D+π−, where the scalar meson D0(0+) is considered as a four-quark state (cd)(ūd̄). Although our results for the mass and partial decay width are smaller than the mass and the total decay width of the broad scalar meson D∗0 0 (2308) reported by BELLE Collaboration, we can not discard the possibility that the BELLE’s resonance can be interpreted as the four-quark state studied here.

A ug 2 00 8 Another tetraquark structure in the π + χ c 1 invariant mass distribution
In this article, we assume that the mesons in the πχc1 invariant mass distribution are scalar hidden charmed tetraquark states and calculate their masses with the QCD sum rules. The numerical result indicates that the masses are about MZ = (4.48 ± 0.12)GeV. In previous work, we observe that the masses of the vector hidden charmed tetraquark states are about MZ = (4.81±0.11)GeV or MZ = (4.83±0.1...
متن کاملThe qq spectra and the structure of the scalar mesons
The qq spectrum is studied within a chiral constituent quark model. It provides with a good fit of the available experimental data from light (vector and pseudoscalar) to heavy mesons including some recent results on charmonium. The 0 light mesons and the new D states measured at different factories cannot be described as qq̄ pairs and a tetraquark structure is suggested.

In this article, we assume that the mesons in the πχc1 invariant mass distribution are scalar hidden charmed tetraquark states and study their masses with the QCD sum rules. The numerical result indicates that the mass is about MZ = (4.19 ± 0.17)GeV, which is consistent with the experimental data. The hidden charmed mesons Z1 and Z2 may be tetraquark states, other possibilities, such as hadro-c...

In this article, we interpolate the vector hidden charmed tetraquark state with the Cγ5 − Cγμγ5 type current, and calculate its mass with the QCD sum rules. The numerical result indicates that the mass is about MZ = (4.09 ± 0.11)GeV, while the C − Cγμ type interpolating current leads to the mass aboutMZ = (4.22±0.10)GeV; they are consistent with the experimental data on the πχc1 invariant mass ...

The qq spectrum is studied within a chiral constituent quark model. It provides with a good fit of the available experimental data from light (vector and pseudoscalar) to heavy mesons. The new D states measured at different factories are studied. The 0 ++ light mesons are analyzed as q ¯ q pairs or tetraquark structures.
