Quantum Gravity, Strings, and Hidden Energy Scales
Fernando Marchesano (Madrid, IFT)

String theory has been used to construct models of particle physics and cosmology in which Quantum Gravity is automatically incorporated. Such models always present certain features, whose importance was up to now deemed secondary. But what if they were an actual imprint of Quantum Gravity into high energy physics?

The Swampland Programme aims to unveil the general constraints that Quantum Gravity imposes on effective field theories of particle physics and cosmology, in order to derive actual predictions. In this talk I will consider those proposals that describe the energy scales that appear all the way up to the Planck mass, describe their implications for models of high energy physics, and discuss the current open problems that stem from them.
