三电荷单极子与磁夸克

Triply Charged Monopole and Magnetic Quarks

George Lazarides, Qaisar Shafi

摘要:

我们描述的内部组成的拓扑稳定的带磁荷$6π/e$产生的三位一体对称性$SU(3)_c\times SU(3)_L\times SU(3)_R$($G$)的自发破缺。由于这种磁不带色磁荷,狄拉克量子化条件要求电荷为$6π/e$。从$G$到标准模型的破缺经过了许多步骤,并产生了所需的拓扑稳定的重子(“磁性重子”),由三个受限的单极子组成。禁闭单极子(“磁夸克”)每个都携带库仑磁通量和磁通量管的组合,因此它们不以孤立状态存在。我们还展示了由这些磁夸克组成的更精细的结构(“尖牙项链”)。与超重的$SU(5)$相比,它携带着$2π/e$的磁荷和色磁荷,三重化的质量可能在TeV范围内,在这种情况下,它可能在LHC及其计划的升级中获得。

英文摘要:

We describe the internal composition of a topologically stable monopole carrying a magnetic charge of $6π/e$ that arises from the spontaneous breaking of the trinification symmetry $SU(3)_c\times SU(3)_L\times SU(3)_R$ ($G$). Since this monopole carries no color magnetic charge, a charge of $6π/e$ is required by the Dirac quantization condition. The breaking of $G$ to the Standard Model occurs in a number of steps and yields the desired topologically stable monopole ("magnetic baryon"), consisting of three confined monopoles. The confined monopoles ("magnetic quarks") each carry a combination of Coulomb magnetic flux and magnetic flux tubes, and therefore they do not exist as isolated states. We also display a more elaborate configuration ("fang necklace") composed of these magnetic quarks. In contrast to the $SU(5)$ monopole which is superheavy and carries a magnetic charge of $2π/e$ as well as color magnetic charge, the trinification monopole may have mass in the TeV range, in which case it may be accessible at the LHC and its planned upgrades.
