摘要: 本文简要介绍国内外高能物理发展的最新状况，概述了国外对顶夸克存在的证据、电弱相互作用的精密检验及重味物理与轻子物理的进展．另外，还介绍了在北京谱仪上，有关τ质量测量、Ｊ／ψ衰变性质、ψ衰变性质及Ｄｓ衰变性质方面的最新结果． The recent experiment status of high energy physics in the world are presented briefly.The evidence for the TOP quark,precision test of EW interaction, heavy flavor physics and lepton physics are summarized in the first part. The second part introduces the new results on τ mass measurement,ψ decay,Ds decay and J/ψ decay performance from BES.
