Pion-nucleon elastic scattering amplitude within covariant baryon chiral perturbation theory up to level
Yun-hua Chen, De-liang Yao, H. Q. Zheng
The calculation on pion-nucleon elastic scattering amplitude in EOMS scheme within covariant baryon chiral perturbation theory is reviewed. Numerical fits to partial wave…
On the Nature of X(4260)
L. Y. Dai, Meng Shi, Guang-Yi Tang +1
We study the property of resonance by re-analyzing all experimental data available, especially the cross section data. The…
Positivity constraints on LECs of PT lagrangian at $\cO(p^6)$ level
Zhi-Hui Guo, Ou Zhang, H. Q. Zheng
Positivity constraints on the LECs of $\cO(p^6)$ PT lagrangian are discussed. We demonstrate that the constraints are automatically satisfied inside the Mandelstam triangle for…
Investigations on the Property of and Resonances in Process
X. G. Wang, O. Zhang, L. C. Jin +2
Using dispersion relation technique and experimental data, a coupled channel analysis on process is made. Di-photon coupling of and resonances are e…
Study of J/Psi decays into eta Kstar Kstar-bar
The BES Collaboration, M. Ablikim
We report the first observation of $\mPJpsi \to \mPeta\mPKst\mAPKst$ decay in a $\mPJpsi$ sample of 58 million events collected with the BESII detector. The branching fraction is d…
value measurements for annihilation at 2.60, 3.07 and 3.65 GeV
The BES Collaboration, M. Ablikim
Using a data sample with a total integrated luminosity of 10.0 pb collected at center-of-mass energies of 2.6, 3.07 and 3.65 GeV with BESII, cross sections for anni…
