Positivity constraints on the low-energy constants of the chiral pion-nucleon Lagrangian
Juan Jose Sanz-Cillero, De-Liang Yao, Han-Qing Zheng
Positivity constraints on the pion-nucleon scattering amplitude are derived in this article with the help of general S-matrix arguments, such as analyticity, crossing symmetry and…

Radiative transition processes of light vector resonances in a chiral framework
Yun-Hua Chen, Zhi-Hui Guo, Han-Qing Zheng
Within the framework of chiral effective field theory, we study various electromagnetic processes with light vector resonances: , $e^{+}e^{-}\to K^{\ast}(892)K…

Studies on X(4260) and X(4660) particles
Meng Shi, De-Liang Yao, Han-Qing Zheng
Studies on the X(4260) and X(4660) resonant states in an effective lagrangian approach are reviewed. Using a Breit--Wigner propagator to describe their propagation, we find that th…
