Causality Constraints on Gravitational Effective Field Theories
Claudia de Rham, Andrew J. Tolley, Jun Zhang
We consider the effective field theory of gravity around black holes, and show that the coefficients of the dimension-8 operators are tightly constrained by causality consideration…
Reverse Bootstrapping: IR lessons for UV physics
Lasma Alberte, Claudia de Rham, Sumer Jaitly +1
S-matrix bootstrap and positivity bounds are usually viewed as constraints on low-energy theories imposed by the requirement of a standard UV completion. By considering graviton--p…
Scattering Amplitudes for Binary Systems beyond GR
Mariana Carrillo-González, Claudia de Rham, Andrew J. Tolley
Amplitude methods have proven to be a promising technique to perform Post-Minkowskian calculations used as inputs to construct gravitational waveforms. In this paper, we show how t…
