Understand
We show that theories that exhibit classicalization phenomenon cease to do so as soon as they are endowed a Wilsonian weakly-coupled UV-completion that restores perturbative unitarity, despite the fact that such UV-completion does not change the leading structure of the effective low-energy theory.
- For example, a Chiral Lagrangian of Nambu-Goldstone bosons (pions), with or without the Higgs (QCD) UV-completion looks the same in zero momentum limit, but the latter classicalizes in high energy scattering, whereas the former does not.
- Thus, theory must make a definite choice, either accept a weakly-coupled UV-completion or be classicalized.
- The UV-awareness that determines the choice is encoded in sub-leading structure of effective low-energy action.
