摘要

An international research consortium announced on January 6 the observation of a resonant state at the upgraded Beijing Spectrometer (BESII). The discovery, which was reported in the Dec. 31, 2005 Issue of the Physical Review Letters, has aroused a broad interest from the world high energy physics community. The BES is a large-scale, general purpose solenoidal detector installed on the Electron Positron Collider (BEPC) on the campus of the CAS Institute of High Energy PhysicsilHEP). The BES International Collaboration, which is composed of the physicists and graduate students from IHEP and more than 20 other domestic universities and research institutions, as well as from the U.S., the U.K., Japan and Sweden, is dedicated to the study of tau lepton and charm quark physics. J/PSI particle, a composite of charm quark and anti-charm quark, was discovered simultaneously at the Brookhaven National Laboratory and the Stanford Linear Accelerator Center in the United States in 1974 by Prof. S.Ting and Prof. B.Richter who were awarded the Nobel- Prize for the discovery. The study of J/PSI decays provides physicists an ideal laboratory for the study of light hadron spectroscopy and charm physics.
