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…
Baryon Fields with U_L(3) times U_R(3) Chiral Symmetry III: Interactions with Chiral (3,3_bar)+(3_bar,3) Spinless Mesons
Hua-Xing Chen, V. Dmitrasinovic, Atsushi Hosaka
Three-quark nucleon interpolating fields in QCD have well-defined SU_L(3)*SU_R(3) and U_A(1) chiral transformation properties, viz. [(6,3)+(3,6)], [(3,3_bar)+(3_bar,3)], [(8,1)+(1,…
Pseudoscalar Mesons in the SU(3) Linear Sigma Model with Gaussian Functional Approximation
Hua-Xing Chen, V. Dmitrasinovic, Hiroshi Toki
We study the SU(3) linear sigma model for the pseudoscalar mesons in the Gaussian Functional Approximation (GFA). We use the SU(3) linear sigma model Lagrangian with nonet scalar a…
