| 英文摘要 | Provided the enhancement in the pp spectrum in radiative decay j/psi -> yp (p) over bar observed by the bes collaboration is due to an existence of a p (p) over bar molecular state, we calculate its binding energy and lifetime in the linear sigma model. concretely, we consider a possibility that the enhancement is due to a pp resonance which is in either s-wave or p-wave structure and compare our results with the data. moreover, p (p) over bar can annihilate at s-channel which is absent in deuteron, thus by studying the total width of the p (p) over bar bound state, we may gain more information about the linear sigma model and some concerned issues. |
