额外费米子产生的精度约束

Precision Constraints on Extra Fermion Generations

Jens Erler, Paul Langacker

摘要:

人们对额外的费米子世代的可能性重新产生了兴趣。与此同时,在相关的电弱精度约束方面,特别是在对几个低能实验的解释方面,也发生了重大变化。我们总结了额外的家庭的各种动机,并根据最新的电弱精密数据进行分析。

英文摘要:

There has been renewed interest in the possibility of additional fermion generations. At the same time there have been significant changes in the relevant electroweak precision constraints, in particular, in the interpretation of several of the low energy experiments. We summarize the various motivations for extra families and analyze them in view of the latest electroweak precision data.
