Description
In this talk, I will review different approaches to testing Effective Field Theories (EFTs). First, I will briefly review how amplitude techniques can allow us to extract classical observables during the merge of a black hole binary for generic EFTs of gravity including minimal and non-minimal couplings. In the second half of my talk, I will focus on how to obtain bounds on Wilson coefficients of EFTs from the requirement of physical principles. I will compare the strength of positivity and causality bounds and show how applying both can be a powerful tool. Both of these techniques allow us to test EFTs effectively when comparing theoretical predictions to observations.
