BPS Cho-Maison monopole

We present exact solutions to the Cho-Maison magnetic monopole in a family of effective electroweak models that have a Bogomol'nyi-Prasad-Sommerfield limit. We find that the lower bound to the mass of the magnetic monopole is M >= 2 Pi v/g approximate to 2.37 TeV. We argue that this bound holds universally, not just in theories with a BPS limit.
