论文摘要
夸克和叶子的最小标准模型使用一组矢量般的费米子进行扩展，以允许Baryon Number $ b $成为一个测量的$ u（1）_b $对称。新粒子的$ b $分配是通过与已知夸克通过颜色三重标量标量diquark的可重新分解相互作用来确定的。标量$ u（1）_b $的自发破坏，$ b = 3 $会导致保守的残留全局$ b $对称性。具有$ b = 2 $的单线中性标量是可能的长寿候选人。
The minimal standard model of quarks and leptons is extended with a set of vectorlike fermions to allow baryon number $B$ to become a gauged $U(1)_B$ symmetry. The $B$ assignments of the new particles are determined by renormalizable interactions with the known quarks through a color triplet scalar diquark. The spontaneous breaking of $U(1)_B$ by a scalar with $B=3$ results in a conserved residual global $B$ symmetry. A singlet neutral scalar with $B=2$ is a possible long-lived dark-matter candidate.
