摘要
美国费米国家实验室的CDF实验组在对撞能量1.8 GeV的TEVATRON质子-反质子对撞机上观察到了顶夸克的证据。给出顶夸克的质量为174±10_(-12)^(+13)GeV/c^2,产生截面为13.9_(-4.8)^(+6.)
CDF collaboration has observed the evidence of top quark in 1. 8 TeV pp collisions, on the Tevatron at Fermi National Lab. From the observed top candidate events, the top mass is derived to be 174±10_(-12)^(+13) GeV/c2,the cross section of top production is 13. 9_(-4.8)^(+6.1) Pb.
