Neutral Magnetic Monopole in the Standard Model

Y. M. Cho

Abstract

The standard model has the electroweak monopole which has the magnetic charge $4π/e$, as a hybrid between the Dirac and 'tHooft-Polyakov monopoles. We argue that it may have new type of monopoles, in particular the neutral monopole (``the Z monopole") which is electromagnetically neutral but has the neutral magnetic charge $4π/\be$, where $\be$ is the neutral charge. The mass of the new monopole could be less than the Cho-Maison monopole, around 3.28 TeV. We show how to construct the neutral monopole and clarify the origin of the topology of the new monopole. We discuss the implications of the new monopoles in physics.

Abstract

The standard model has the electroweak monopole which has the magnetic charge , as a hybrid between the Dirac and 'tHooft-Polyakov monopoles. We argue that it may have new type of monopoles, in particular the neutral monopole (``the Z monopole") which is electromagnetically neutral but has the neutral magnetic charge , where is the neutral charge. The mass of the new monopole could be less than the Cho-Maison monopole, around 3.28 TeV. We show how to construct the neutral monopole and clarify the origin of the topology of the new monopole. We discuss the implications of the new monopoles in physics.

  • Figure 1: The neutral monopole solution which has the magnetic charge $4\pi/\bar{e}$ in the standard model. The new solution is shown in red curves, which also describe the Cho-Maison monopole which has only the W boson dressing. For comparison we plot the well known Cho-Maison monopole solution which has the Higgs and W boson dressing in black curves.
