STAG Seminar: "Pulling oneself over the fence: a bootstrap for quantum gravity"
Asymptotic freedom is a key ingredient in the successful construction of the Standard Model of particle physics. It has been conjectured long ago that gravity may equally well fit into this picture - despite its notorious perturbative non-renormalisability - provided that the theory turns out to be asymptotically safe. We contrast asymptotic freedom with asymptotic safety and propose a self-consistent search strategy for the latter. Results for a simplified version of quantum gravity and implications for the asymptotic safety conjecture are discussed.
