Neutral Magnetic Monopole in the Standard Model

TL;DR

This paper proposes a new type of neutral magnetic monopole within the Standard Model, called the Z monopole, which is electromagnetically neutral but carries a neutral magnetic charge, with potential implications for particle physics.

Contribution

It introduces the concept of a neutral Z monopole in the Standard Model, detailing its construction, topology, and potential mass, expanding the understanding of monopoles beyond existing models.

Findings

The neutral Z monopole has a magnetic charge of 4π/β.

Its mass could be around 3.28 TeV, less than the Cho-Maison monopole.

The paper clarifies the topology and construction of the neutral monopole.

Abstract

The standard model has the electroweak monopole which has the magnetic charge $4\pi/e$, 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 $4\pi/\be$, 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.
