寻找顶夸克的漫长过程

A LONG WAY TO SEARCH FOR TOP QUARK

本文描述寻找顶夸克的漫长过程。从70年代末开始,美国的PEP,德国的PETRA,80年代日本的TRISTAN,欧洲核子中心CERN的SP PS质子反质子对撞机,90年代的CERN的LEP大型电子正电子对撞机,最后于1997年才由美国费米国家实验室的D0和CDF国际合作组找到了顶夸克存在的证据,并给出了顶夸克的质量为:174.3±3.2±4.0GeV。人们可以从这段历史获得有益的启示。

This paper describes the long way to search for the top quark. From PEP in the US and PETRA in Germany, at the end of 70's, to SPS in 80's and LEP in 90's from CERN, the top quark was finally found in 1997 by D0 and CDF in Fermi Lab, its mass given to be M_t=174.3±3.2±4.0 GeV. One can gain enlightenment from this history.
