The Fröhlich-Morchio-Strocchi mechanism: A underestimated legacy

Abstract

There is an odd tension in electroweak physics. Perturbation theory is extremely successful. At the same time, fundamental field theory gives manifold reasons why this should not be the case. This tension is resolved by the Fröhlich-Morchio-Strocchi mechanism. However, the legacy of this work goes far beyond the resolution of this tension, and may usher in a fundamentally and ontologically different perspective on elementary particles, and even quantum gravity.
