Cho-Maison magnetic monopole: BPS limit and lower mass bound

Abstract

We construct a class of effective extensions of the Standard Model that support finite-mass Cho-Maison magnetic monopole in the Bogomol'nyi-Prasad-Sommerfield (BPS) limit. We present an example of exact analytic monopole solution and derive a universal lower mass bound $M\ge 2\pi v/g\approx 2.37\mathrm{TeV}$ of the Cho-Maison magnetic monopole.
