Renormalization-Group & Gauge-Sector Foundations
Abstract
Computes one-loop functional-RG flow for gravity + scalaron and shows how an SU(2) gauge field emerges from twistor-scalar dynamics.
Key Results
- Derives coupled β-functions for {G, Λ, α, λ} and finds a UV non-Gaussian fixed point with two relevant directions
- Demonstrates SU(2) gauge symmetry arises naturally from a triplet scalar in the twistor formalism
- Confirms matter couplings are irrelevant at the fixed point, tightening RFT predictivity
