SOFIA: Singularities of Feynman Integrals Automatized
Miguel Correia, Mathieu Giroux, Sebastian Mizera
We introduce SOFIA, a Mathematica package that automatizes the computation of singularities of Feynman integrals, based on new theoretical understanding of their analytic structure…
Records from the S-Matrix Marathon: Asymptotic Observables
Simon Caron-Huot, Mathieu Giroux, Holmfridur S. Hannesdottir +2
These lectures introduce the notion of asymptotic observables, which are classes of measurable quantities predicted by quantum field theory. In gapped theories with trivial infrare…
Records from the S-Matrix Marathon: Gravitational Physics from Scattering Amplitudes
Miguel Correia, Holmfridur S. Hannesdottir, Giulia Isabella +5
These lecture notes explain how classical gravitational physics emerges from scattering amplitudes. We emphasize the role of different kinematic regimes in probing various aspects…
Records from the S-Matrix Marathon: Tasty Bits of Several Complex Variables
Sean N. Curry, Jiří Lebl, Mathieu Giroux +3
We will cover the basics of several complex variables in 4 lectures: Basic properties of holomorphic functions in several variables, the notion of pseudoconvexity, CR functions and…
Records from the S-Matrix Marathon: A Timeless History of Time
Mang Hei Gordon Lee, Enrico Pajer, Mathieu Giroux +3
By directly probing the initial conditions of our universe, cosmological surveys offer us a unique observational handle on quantum field theory in curved spacetime with dynamical g…
Records from the S-Matrix Marathon: Observables in Expanding Universes
Paolo Benincasa, Mathieu Giroux, Holmfridur S. Hannesdottir +3
Observables in expanding universes are crucial to understand the physics of the early universe. In these lectures, we review some recent progress in understanding their mathematica…
Recursive Landau Analysis
Simon Caron-Huot, Miguel Correia, Mathieu Giroux
We propose a recursive method that makes use of the basic principle of unitarity to calculate the Landau singularities of n-point scattering amplitudes directly in kinematic space.…
Crossing beyond scattering amplitudes
Simon Caron-Huot, Mathieu Giroux, Holmfridur S. Hannesdottir +1
We find that different asymptotic measurements in quantum field theory can be related to one another through new versions of crossing symmetry. Assuming analyticity, we conjecture…
