(04.11.) Where is String Theory ?

I will review the (numerical) S-matrix Bootstrap approach to scattering amplitudes. In particular, I will explain how this approach can be used to bound the space of Wilson coefficients in Effective Field Theories (EFT). I will focus on the application to supergravity in 10 spacetime dimensions (https://arxiv.org/abs/2102.02847). Remarkably, strongly coupled string theory seems to saturate the bounds imposed by Lorentz invariance, unitarity and causality.
