SMEFT beyond O(1/Lambda^2)

28 Jul 2021, 10:30


Parallel session talk Higgs Physics T07-T09: Combined: Top, Electroweak and Higgs Physics


Adam Martin (University of Notre Dame)


"In this talk I’ll talk about truncation errors in the Stadard Model Efftective Field Theory (SMEFT) paradigm — meaning errors from higher terms in the EFT expansion. The main tool I’ll use to tackle this type of uncertainty is special operator basis called the “Geometric SMEFT”, or geoSMEFT. I will explain the benefits of the geoSMEFT basis and go through some preliminary studies of the impact of O(1/Lambda^4) terms on observables such as Higgs partial width to photons and Z-pole physics.”
