论文摘要
我们构建无异常的$ u（1）_1 \ times u（1）_2 \ times ... \ times u（1）_m $ $ $ $量规扩展。为了执行此构建，我们将无异常的$ u（1）$扩展到一个和两个费米子家族。免费参数的可用性，这些参数可在费米电荷的方程式中线性输入以及大量不同类别的扩展名，可以帮助其他模型构建者对解决粒子物理问题的使用感兴趣。
We construct anomaly-free $U(1)_1\times U(1)_2\times...\times U(1)_m$ gauge extensions of the Standard Model. To perform this construction we put together anomaly-free $U(1)$ extensions of one and two families of fermions. The availability of free parameters that enter linearly in the equations for the fermion charges and the large number of different classes of extensions may help other model builders interested in their use to solve problems of particle physics.
