Understanding Possible Proton-Antiproton Enhancement Observed by BES Collaboration*

We comment on the quantum numbers and decay channels of the proton-antiproton enhancement observed by BES Collaboration. Based on the general symmetry consideration and available experimental information, we suggest that the quantum number of this possible signal is very likely to be which cannot decay into final states Besides its dissociation into the other important mesonic decay modes could be Experimental search of this signal in these meson final states is strongly called for.

X（1835）： A Possible Baryonium？

We point out that (1) the large

coupling and suppressed mesonic coupling of X(1835) and (2) the suppression of the three-body strange final states strongly indicate that X(1835) may be a
