Renormalisation group and the Planck scale
Daniel F. Litim
TL;DR
This paper explores the application of the renormalisation group approach to gravity, connecting it to Weinberg's asymptotic safety scenario, and reviews its implications for particle physics and cosmology.
Contribution
It provides an overview of the renormalisation group method in quantum gravity and discusses recent results related to the Planck scale and asymptotic safety.
Findings
Support for the asymptotic safety scenario in quantum gravity
Implications for particle physics models at high energies
Cosmological applications of renormalisation group techniques
Abstract
I discuss the renormalisation group approach to gravity, its link to Steven Weinberg's asymptotic safety scenario, and give an overview of results with applications to particle physics and cosmology.
