I will exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned. These theories possess bounded target…
On large scales the Universe is well described by a cosmological model where matter primarily comprises cold dark matter (CDM), a single collision-less particle species with negligible primordial thermal dispersion.…
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 constraints on the Wilson…
Observations of the large-angular-scale autocorrelation function and power spectrum of the cosmic microwave background (CMB) over the last 30 years have consistently provided hints that our standard LCDM cosmological…
