Planck Scale Cosmology and Resummed Quantum Gravity

TL;DR

This paper applies amplitude-based resummation techniques to Einstein's quantum gravity, providing first-principles predictions for the UV fixed points of gravitational constants and linking to asymptotic safety models in Planck scale cosmology.

Contribution

It introduces a novel resummation approach to quantum gravity that yields predictive UV fixed points, connecting fundamental theory with phenomenological models.

Findings

Predicted UV fixed-point values for gravitational and cosmological constants.

Established connections between resummed quantum gravity and asymptotic safety.

Provided a first-principles derivation of Planck scale cosmological parameters.

Abstract

We show that, by using amplitude-based resummation techniques for Feynman's formulation of Einstein's theory, we get quantum field theoretic 'first principles' predictions for the UV fixed-point values of the dimensionless gravitational and cosmological constants. Connections to the phenomenological asymptotic safety analysis of Planck scale cosmology by Bonanno and Reuter are discussed.
