Pseudoscalar Meson and Decuplet Baryon Scattering Lengths
Zhan-Wei Liu, Yan-Rui Liu, Shi-Lin Zhu
We have systematically calculated the S-wave pseudoscalar meson and decuplet baryon scattering lengths to the third order in the small scale expansion scheme of the heavy baryon ch…
Novel charmonium-like structures in the and invariant mass spectra
Xiang Liu, Zhi-Gang Luo, Shi-Lin Zhu
Stimulated by the new evidence of Y(4274) observed in the invariant mass spectrum, we first propose the charmonium-like state Y(4274) as the S-wave $D_s\bar{D}_{s0}(2317)+h.…
The Strong Decay Patterns of the Exotic Hybrid Mesons
Peng-Zhi Huang, Hua-Xing Chen, Shi-Lin Zhu
We calculate the coupling constants of the decay modes within the framework of the light-cone QCD sum rule. Then we calculate…
The Decay Properties of the 1^{-+} Hybrid State
Hua-Xing Chen, Zi-Xing Cai, Peng-Zhi Huang +1
Within the framework of the QCD sum rules, we consider the three-point correlation function, work at the limit q^2 -> 0 and m_π-> 0, and pick out the singular term ~ {1\over q^2} t…
The Vector and Axial-Vector Charmonium-like States
Wei Chen, Shi-Lin Zhu
After constructing all the tetraquark interpolating currents with and in a systematic way, we investigate the two-point correlation functio…
The molecular systems composed of the charmed mesons in the doublet
Lei-Lei Shen, Xiao-Lin Chen, Zhi-Gang Luo +4
We study the possible heavy molecular states composed of a pair of charm mesons in the H and S doublets. Since the P-wave charm-strange mesons and are…
