Triply Charged Monopole and Magnetic Quarks

Abstract

We describe the internal composition of a topologically stable monopole carrying a magnetic charge of $6\pi /e$ 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 $6\pi /e$ 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 $2\pi /e$ 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.
