BaBar合作组在e+ e-→Фf0(980)衰变道的Фf0(980)不变质量谱上发现了一个新强子态Y(2175),随后,BES和Belle实验都相继证实了这一发现.与此同时,理论家们也对Y(2175)的内部性质进行了大量的研究.本工作对目前Y(2175)在实验和理论上的进展进行了详细的评述.同时,讨论了在Фf0(980)不变质量谱中的2175 MeV以上能区寻找其它增长结构的可能性.
Since the BaBar Collaboration announced a new hadron Y(2175)observed in the φ(980)invariant mass spectrum of e+e-→φf0(980),both BES and Belle confirmed BaBar's observation.Meanwhile,the theorist also carries 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 publishedexperimental data of Y(2175),we also discuss the possibility of searching for other enhancement structuresafter 2175 MeV in the φf0(980)invariant mass spectrum.
