Primordial cosmology from quantum gravity with purely virtual particles
4 years ago

Online talk by D. Anselmi for the Kavli Institute for Cosmology, Institute of Astronomy, University of Cambridge
Abstract: I introduce the concept of purely virtual particle, or fakeon, and show how to use it to make sense of quantum gravity as a quantum field theory. Then I discuss novel features of the classical limit and derive predictions in inflationary cosmology that could be tested in the forthcoming years, paying special attention to the effects of fakeons on perturbation spectra
