The gravitational S-matrix and dispersion relations

Download to your calendar using vCal

If you have a question about this talk, please contact Bernardo Zan .

I will review the basic properties of gravitational scattering and discuss their interplay with the principles of S-matrix theory. I will argue that gravitational amplitudes admit twice-subtracted dispersion relations, and demonstrate how these can be used to derive novel constraints on the low-energy gravitational effective field theories and their UV completions.
