TITLE: Gravity as Quantum Field Theory
Abstract: From a theoretical perspective, general relativity comes with a number of structural deficits pointing at the incompleteness of the theory: solutions of Einstein’s equations rather generically exhibit spacetime singularities and gravity-mediated scattering amplitudes grow without bound when the energy is increased. In this talk, I will introduce the quantum effective action for gravity as a tool to systematically investigate cures to these shortcomings. The talk serves as a gentle introduction to the form-factor approach to quantum gravity initiated in arXiv:1907.02903 [hep-th] and outlines the theoretical and phenomenological perspectives opened by this viewpoint.
