Light Scalar Meson sigma(600) in QCD Sum Rule with Continuum
Hua-Xing Chen, Atsushi Hosaka, Hiroshi Toki +1
The light scalar meson sigma(600) is known to appear at low excitation energy with very large width on top of continuum states. We investigate it in the QCD sum rule as an example…
Baryon Fields with U_L(3) \times U_R(3) Chiral Symmetry: Axial Currents of Nucleons and Hyperons
Hua-Xing Chen, V. Dmitrasinovic, Atsushi Hosaka
We use the conventional F and D octet and decimet generator matrices to reformulate chiral properties of local (non-derivative) and one-derivative non-local fields of baryons consi…
Light vector meson and heavy baryon strong interaction
Peng-Zhi Huang, Hua-Xing Chen, Shi-Lin Zhu
We calculate the coupling constants between the light vector mesons and heavy baryons within the framework of the light-cone QCD sum rule in the leading order of heavy quark effect…
The Possible J^{PC}=0^{--} Exotic State
Chun-Kun Jiao, Wei Chen, Hua-Xing Chen +1
In order to explore the possible existence of the exotic state, we have constructed the tetraquark interpolating operators systematically. As a byproduct, we notice the $0…
