Seminar Non-locality in QFT due to Quantum Effects in Gravity

Contatto di riferimento: Barbara Simoni

Partecipanti: Dr. Calmet Xavier (University of Sussex - UK)

Abstract: In this talk I discuss how effective field theory techniques which are commonly used in high energy physics can be adapted to quantum gravity. I show that an effective theory approach  to quantum gravity combined with perturbative unitarity techniques  can lead to interesting insights into the energy scale of quantum gravity. One interesting feature of our investigation is the appearance of non-local effects around the Planck scale.
