TL;DR

This paper estimates the mass of the electroweak monopole to be around 4 TeV using scaling arguments and constructs finite energy dyon solutions, suggesting it could be detectable at the LHC.

Contribution

It introduces a finite energy analytic dyon solution as a regularized electroweak monopole with a mass scale accessible at current colliders.

Findings

Electroweak monopole mass estimated at ~4 TeV

Constructed finite energy dyon solutions

Electroweak monopole potentially detectable at LHC

Abstract

The recent MoEDAL experiment at LHC to detect the electroweak monopole makes the theoretical prediction of the monopole mass an urgent issue. We discuss different ways to estimate the mass of the electroweak monopole. We first present a scaling argument which indicates that the mass of the electroweak monopole to be around 4 TeV. To justify this we construct finite energy analytic dyon solutions which could be viewed as the regularized Cho-Maison dyon, modifying the coupling strengths of the electromagnetic interaction of $W$-boson in the standard model. Our result demonstrates that a genuine electroweak monopole whose mass scale is much smaller than the grand unification scale can exist, which can actually be detected at the present LHC.
