Gauge-Fixed Scalaron–Twistor Action & Feynman Rules

Abstract

Derives the completely gauge-fixed action for the scalaron–twistor unified theory, lists all propagators and vertices, and verifies 1-loop renormalizability and BRST invariance, furnishing a ready reference for perturbative calculations.

Key Results

• Provides closed-form Feynman rules for gravity, gauge and scalar sectors
• Demonstrates BRST symmetry preserves gauge independence of S-matrix
• SymPy notebook cross-checks sample scattering amplitudes for consistency
