Price of asymptotic safety
journal contribution
posted on 2023-06-09, 18:09 authored by Andrew D Bond, Daniel LitimDaniel LitimAll known examples of four dimensional quantum ?eld theories with asymptotic freedom or asymptotic safety at weak coupling involve non-abelian gauge interactions. We demonstrate that this is not a coincidence: no weakly coupled ?xed points, ultraviolet or otherwise, can be reliably generated in theories lacking gauge interactions. Implications for particle physics, critical phenomena, and conformal ?eld theory, are indicated.
