The Universal One-Loop Effective Action
Aleksandra Drozd, John Ellis, Jérémie Quevillon +1
We present the universal one-loop effective action for all operators of dimension up to six obtained by integrating out massive, non-degenerate multiplets. Our general expression m…
Isospin-violating dark-matter-nucleon scattering via two-Higgs-doublet-model portals
Aleksandra Drozd, Bohdan Grzadkowski, John F. Gunion +1
We show that in a multi-Higgs model in which one Higgs fits the LHC 125 GeV state, one or more of the other Higgs bosons can mediate DM-nucleon interactions with maximal DM isospin…
Comparing EFT and Exact One-Loop Analyses of Non-Degenerate Stops
Aleksandra Drozd, John Ellis, Jérémie Quevillon +1
We develop a universal approach to the one-loop effective field theory (EFT) using the Covariant Derivative Expansion (CDE) method. We generalise previous results to include broade…
