Gravity - Renormalizing the Non-Renormalizable
Dr. Frank Saueressig (Institut für Physik, Universität Mainz)

Weinbergs asymptotic safety conjecture proposes that gravity constitutes a consistent and predictive Quantum Field Theory within Wilsons generalized framework of renormalization. The central ingredient in this scenario is a non-trivial fixed point of the gravitational renormalization group flow which controls the high-energy behavior of the theory and ensures the absence of unphysical UV divergences. The talk gives a pedagogical introduction to this scenario, introducing the functional renormalization group equations central to its exploration before reviewing the status of the asymptotic safety program.
