Positivity bounds on Effective Field Theories with spontaneously broken Lorentz Invariance

06.05.2022 11:50 – 12:50

In the last few years, there has been rapid progress in deriving positivity bounds on the coefficients of operators on low-energy Effective Field Theories (EFT's), under the assumption that such low energy EFT's have a standard UV completion. I will present a formalism to derive analogous bounds in the case of EFT's that spontaneously break boosts, and I will explicitly work out an example.
