EFT Validity and Truncation Uncertainty from few Nuisance Parameters
Benoît Assi, Adam Martin, William Shepherd
An observable in an Effective Field Theory (EFT) is an expansion in a set of small parameters, no different than any other perturbation series. Truncating such a series expansion l…
Higgs decays to four leptons to in SMEFT
Mario Flores-Hernandez, Adam Martin
We study the decays and within the SMEFT framework and including effects up…
Probing EFT breakdown in the tails of observables
Daniel Gillies, Andrea Banfi, Adam Martin
In this letter, we test clipping effective field theory (EFT) simulations as a method of ensuring EFT validity. The procedure imposes that, at the level of the simulation, the inva…
Energy-Enhanced Expansion of the Standard Model Effective Field Theory
Benoît Assi, Adam Martin
We formalize energy-scaling arguments in the Standard Model Effective Field Theory (SMEFT) to estimate effects of operators up to dimension ten. Introducing a classification based…
Energy-Enhanced Dimension Eight SMEFT Effects in VBF Higgs production
Benoît Assi, Adam Martin
We study Higgs boson production via vector boson fusion at the LHC, focusing on the process and capturing the leading energy-enhanced contributions within the Stand…
