Abstract

Since the BaBar Collaboration announced a new hadron Y(2175) observed in the f0(980) invariant mass spectrum of e+e-→ f0(980), both BES and Belle confirmed BaBar’s observation. Meanwhile, the theorist also carries out the study to reveal the underlying properties of Y(2175). In this review paper, we give a detailed review of the present experimental and theoretical statues of Y(2175). In terms of the published experimental data of Y(2175), we also discuss the possibility of searching for other enhancement structures
after 2175 MeV in the f0(980) invariant mass spectrum.
