Narrow Results

The results from BEPC/BES were reviewed. The upgrade program of BEPCII is to build a two-ring collider with the luminosity improvement by two orders of magnitudes. The goal of the BEPCII is the precision measurements in the charm physics and search for new physics.

The nuclear physics and particle physics researches in China have a long tradition. BEPC is a milestone of the particle physics in China. The many interesting physics results were obtained from BEPC. Beijing Synchrotron Radiation Facility based on BEPC became the major synchrotron radiation facility in China. The upgrade of BEPC, which will increase the luminosity by two orders of magnitude, is going smoothly. The nonaccelerator based experiments were promoted also. Professor Yang made very important contribution to Chinese physics, especially to promote the large science facilities for the multiple discipline researches. The particle physics faces the great challenges, and meets the great opportunities in the 21st century. The medium-term plan of the particle physics in China was discussed.

Since the first idea of a collider was patented by Rolf Wideröe (1902–1996) in 1943 and the first $e^{+}{e}^{-}$ circular collider, AdA, was successfully principle-proved in LAL, Orsay, France in 1963, different kinds of colliders have been built in the past and planned for the future. In this paper, we will make a rather complete and brief review of the history of different colliders and give a perspective for the future.
