本文研究一个简单的理论，其中重子数和轻子数是局域规范对称。在这个理论中，和是站在同一个立场上的，并且通过增加一个新的费米子代来消除异常。中微子质量的跷跷板机制有一个有趣的认识。此外，有一个自然的抑制味违反夸克和轻子部门，因为规范的对称性和粒子的内容禁止树水平的味道改变中性流涉及夸克或带电轻子。人们还发现，暗物质候选者的稳定性是规范对称性的自动结果。简要讨论了大型强子对撞机的一些约束和信号。
We investigate a simple theory where baryon number () and lepton number () are local gauge symmetries. In this theoryandare on the same footing and the anomalies are canceled by adding a single new fermionic generation. There is an interesting realization of the seesaw mechanism for neutrino masses. Furthermore, there is a natural suppression of flavor violation in the quark and leptonic sectors since the gauge symmetries and particle content forbid tree level flavor changing neutral currents involving the quarks or charged leptons. Also one finds that the stability of a dark matter candidate is an automatic consequence of the gauge symmetry. Some constraints and signals at the Large Hadron Collider are briefly discussed.
