The BABAR experiment has now completed data taking and with an integrated luminosity of 531 fb-1 of e+e-collision data has recorded some 480 million tau-pair ev
We present the physics program of the open charm and heavy c(c-)states above the D(D-)production energy threshold,which will be studied with the BES-Ⅲ detector
A Monte-Carlo Generator Photon Jets(MCGPJ)to simulate Bhabha scattering as well as produc-tion of two charged muons and two photons events is discussed.The theo
