Title (deu)
Causality constraints on EFTs.
Speaker / Lecturer
Sera Cremonini
Lehigh U, Bethlehem
Description (deu)
I will discuss how causality can be used to place bounds on higher derivative corrections to Einstein Maxwell theory. Scattering probe photons off of charged shock waves, we obtain new constrains on the Wilson coefficients parametrizing higher derivative operators. As we will see, gravity weakens the purely field theoretic bounds. Moreover, in four dimensions subtleties arise from IR divergences which need to be regulated, obscuring the physics.
