The Asymptotically Safe Standard Model: From quantum gravity to dynamical chiral symmetry breaking

Understand

We present a comprehensive non-perturbative study of the phase structure of the asymptotically safe Standard Model.

• The physics scales included range from the asymptotically safe trans-Planckian regime in the ultraviolet, the intermediate high-energy regime with electroweak symmetry breaking to strongly correlated QCD in the infrared.
• All flows are computed with a self-consistent functional renormalisation group approach, using a vertex expansion in the fluctuation fields.
• In particular, this approach takes care of all physical threshold effects and the respective decoupling of ultraviolet degrees of freedom.
