Description
Diagrammatic approaches to perturbation theory transformed the practicability of calculations in particle physics. In the case of extended theories of gravity, however, obtaining the relevant diagrammatic rules is non-trivial: we must expand in metric perturbations and around (local) minima of the scalar field potentials, make multiple field redefinitions, and diagonalise kinetic and mass mixings. In this talk, I will motivate these models, introduce the package FeynMG — a Mathematica extension of FeynRules that automates the process described above — and describe an application to a model with unique collider phenomenology.
