摘要:
Since the discoveries ofp ̅p enhancement and X(1835) in J/psi radiatively decaying intoand p ̅ph_c,
respectively, at BESII experiment, these two resonant structures have inspired many theoretical
speculations, including the excited pseudoscalar mesons, baryonium and glueballs. With the 
unprecedented high statistics of J/psi data and the advantages of the excellent performance of
BESIII detector, a series of works on the investigation on the resonant structure around 1.84
GeV was performed. In addition to the new decay modes, the anomalous shape was also observed,
which implies the existence of a narrow resonant structure strongly coupling to p ̅p .  In this
talk, a brief review on the experimental progresses on the study of the resonant structures
around 1.84 GeV at BESIII is presented.
