Workshop
The asymptotic safety scenario for quantum gravity
- Antonio Pereira (Universität Heidelberg, Heidelberg, Germany)
Abstract
General relativity is known to be perturbatively non-renormalizable as a standard quantum field theory. Nevertheless, it is logically possible that an interacting ultraviolet fixed-point exists in the renormalization group flow and quantum gravity can be described as a predictive and UV-complete quantum field theory. Such a possibility was baptized as the asymptotic safety scenario for quantum gravity. In this talk I will discuss this approach, some of its important achievements and supporting evidences and point out present challenges.
