Scalar form factors of semi-leptonic transitions with coupled-channel effects
De-Liang Yao, Miguel Albaladejo, Pedro Fernández-Soler +2
Coupled-channel effects are taken into account for the study of scalar form factors in semi-leptonic and decays, by solving t…
A study of mixing in resonance chiral theory
Yun-Hua Chen, De-Liang Yao, Han-Qing Zheng
The strong and electromagnetic corrections to mixing are calculated using a SU(2) version of resonance chiral theory up to next-to-leading orders in expansion, respec…
Pion-nucleon scattering in covariant baryon chiral perturbation theory with explicit Delta resonances
De-Liang Yao, D. Siemens, V. Bernard +5
We present the results of a third order calculation of the pion-nucleon scattering amplitude in a chiral effective field theory with pions, nucleons and delta resonances as explici…
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…
Analyses of pion-nucleon elastic scattering amplitudes up to in extended-on-mass-shell subtraction scheme
Yun-Hua Chen, De-Liang Yao, H. Q. Zheng
We extend the analysis of elastic pion-nucleon scattering up to level using extended-on-mass-shell subtraction scheme within the framework of covariant baryon chiral pertu…
