Roads to the Standard Model

Alonso, Rodrigo; West, Mia

Abstract

Experimental measurements point at the Standard Model (SM) as the theory of electroweak symmetry breaking, but as we close in on our characterization the question arises of what limits in theory space lead to the SM. The class of theories with this property cannot be ruled out, only constrained to an ever smaller neighborhood of the SM. In contrast, which class of theories does not possess this limit and can therefore potentially be ruled out experimentally? In this work we study both classes and find evidence to support the Standard Model effective field theory being the single road to the Standard Model, theories that fall outside this class keeping a “minimum distance” from the SM characterized by a cutoff of at most 4πv=gSM.
