Studies on phase motion in the process
Z. X. Zhang, J. J. Sanz-Cillero, X. Y. Shen +3
We propose a measurement on the elastic scattering phase shift difference through process in future high statistics BES-III experiment. The de…
On the scalar nonet in the extended Nambu Jona-Lasinio model
Ming-Xian Su, L. Y. Xiao, H. Q. Zheng
We discuss the lightest scalar resonances, , , and in the extended Nambu Jona-Lasinio model. We find that the model parameters can be tuned,…
Renormalizable Sectors in Resonance Chiral Theory: S -> pi pi Decay Amplitude
L. Y. Xiao, J. J. Sanz-Cillero
We develop a resonance chiral theory without any a priori limitation on the number of derivatives in the hadronic operators. Through an exhaustive analysis of the resonance lagrang…
Is the meson dynamically generated?
Zhi-hui Guo, L. Y. Xiao, H. Q. Zheng
We study the problem whether the meson is generated `dynamically'. A pedagogical analysis on the toy O(N) linear sigma model is performed and we find that the large limit…
Is the meson a dynamically generated resonance? -- a lesson learned from the O(N) model and beyond
Zhi-Hui Guo, L. Y. Xiao, H. Q. Zheng
O(N) linear model is solvable in the large limit and hence provides a useful theoretical laboratory to test various unitarization approximations. We find that the large $N_…
Lightest scalars as chiral partners of the Nambu--Goldstone bosons
L. Y. Xiao, H. Q. Zheng, Z. Y. Zhou
We review the spectrum of lightest scalar resonances recently determined using dispersion techniques. The conceptual difference between the pole mass and the bare mass (or the line…
