Contributions from Goldstone-boson-exchange to baryon spectra in the MIT Bag Model
Da-Heng He, Yi-Bing Ding, Xue-Qian Li +1
We discuss contributions of chiral bosons to baryon spectra in the MIT bag model. It is believed that within hadrons, chiral bosons are degrees of freedom which are independent of…

Can the observed enhancement in the mass spectrum of p \bar p in J/ψ\to γp \bar p be interpreted by a possible p \bar p bound state
Xiang Liu, Xiao-Qiang Zeng, Yi-Bing Ding +3
Provided the enhancement in the spectrum in radiative decay observed by the BES collaboration is due to an existence of a molecular stat…

Application of Hypervirial Theorem As Criteria For Accuracy of Variational Trial Wave Function
Yi-Bing Ding, Xue-Qian Li, Peng-Nian Shen
It would be interesting to investigate the accuracy of the results obtained in the variational method, because it is important for studying hadron spectra. One can define some crit…
