Bootstrapping photon scattering in 3+1d* / Hebbar, Aditya (speaker) (École Polytechnique)
The S-matrix bootstrap is a program where one uses the general principles of analyticity, crossing symmetry and unitarity of scattering amplitudes to study the allowed space of quantum field theories. In this talk I will consider the two photon to two photon scattering amplitude and explain how we can use numerical S-matrix bootstrap methods to derive non-perturbative bounds on Wilson coefficients in the low energy effective field theory expansion of photons..

A Bootstrap Bridge Between QCD and Gravity / Guerrieri, Andrea (speaker)
The numerical S-matrix Bootstrap aims at establishing non-perturbative universal bounds on physical observables that can be extracted from scattering amplitudes in any dimension. In this talk, I will focus on dimensions greater or equal to four, focusing on three main topics: no-go theorems for supersymmetric quantum gravity, rigorous model dependent bounds on Higgs couplings, and Bootstrapping the QCD spectrum from physical pion scattering.

Bounds on photon scattering / Häring, Kelian (CERN ; Ecole Polytechnique, Lausanne) ; Hebbar, Aditya (Ecole Polytechnique, CPHT ; Ecole Polytechnique, Lausanne) ; Karateev, Denis (U. Geneva (main) ; Ecole Polytechnique, Lausanne) ; Meineri, Marco (U. Geneva (main) ; Ecole Polytechnique, Lausanne) ; Penedones, João (Ecole Polytechnique, Lausanne)
We study 2-to-2 scattering amplitudes of massless spin one particles in $d=4$ space-time dimensions, like real world photons. We define a set of non-perturbative observables (Wilson coefficients) which describe these amplitudes at low energies. [...]

Bridging Positivity and S-matrix Bootstrap bounds / Elias Miro, Joan (speaker) (ICTP, Trieste)
In this talk I will show how to isolate Effective Field Theory scattering amplitudes in the space of non-perturbative two-to-two amplitudes, using the S-matrix Bootstrap. I will show that this construction leads to novel bounds on operators of dimension less than or equal to six, and specupate about future aplications to the SM EFT..

The revenge of the S-matrix / Paulos, Miguel (speaker) (CERN)
In this talk I will describe recent work aiming to reinvigorate the 50 year old S-matrix program, which aims to constrain scattering of massive particles non-perturbatively. I will begin by considering quantum fields in anti-de Sitter space and show that one can extract information about the S-matrix by considering correlators in conformally invariant theories. [...]
