Electroweak Symmetry Breaking From Monopole Condensation

TL;DR

This paper explores a novel mechanism for electroweak symmetry breaking via monopole-induced fermion condensates, offering an alternative to technicolor with potential implications for fermion mass generation.

Contribution

It introduces models where magnetic hypercharge induces fermion condensates that break electroweak symmetry, differing from traditional approaches by using hypercharge as the driving force.

Findings

Hypercharge-driven condensates can break electroweak symmetry correctly.

Magnetic hypercharge is strongly coupled at TeV scale, enabling condensation.

Heavy top mass can be generated via Rubakov-Callan effect.

Abstract

We examine models where massless chiral fermions with both "electric" and "magnetic" hypercharges could form condensates. When some of the fermions are also electroweak doublets such condensates can break the electroweak gauge symmetry down to electromagnetism in the correct way. Since ordinary hypercharge is weakly coupled at the TeV scale, magnetic hypercharge is strongly coupled and can potentially drive the condensation. Such models are similar to technicolor, but with hypercharge playing the role of the technicolor gauge group, so the standard model gauge group breaks itself. A heavy top mass can be generated via the Rubakov-Callan effect and could thus decouple the scale of flavor physics from the electroweak scale.
