Matching the 2HDM to the HEFT and the SMEFT: Decoupling and Perturbativity
Sally Dawson, Duarte Fontes, Carlos Quezada-Calonge +1
We consider the 2 Higgs Doublet Model (2HDM) and compare two effective field theory (EFT) approaches to it, according to whether the heavy degrees of freedom are integrated out bef…
The Importance of Flavor in SMEFT Electroweak Precision Fits
Luigi Bellafronte, Sally Dawson, Pier Paolo Giardino
Effective field theory tools are essential for exploring non-Standard Model physics at the LHC in the absence of the discovery of new light particles. Predictions for observables a…

Sally Dawson, Admir Greljo, Kristin Lohwasser +16
This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Sev…
Double insertions of SMEFT operators in gluon fusion Higgs boson production
Konstantin Asteriadis, Sally Dawson, Duarte Fontes
Deviations from the Standard Model (SM) can be parameterized in terms of the SM effective field theory (SMEFT), which is typically truncated at dimension-6. Including higher dimens…
Report of the Topical Group on Higgs Physics for Snowmass 2021: The Case for Precision Higgs Physics
Sally Dawson, Patrick Meade, Isobel Ojalvo +78
A future Higgs Factory will provide improved precision on measurements of Higgs couplings beyond those obtained by the LHC, and will enable a broad range of investigations across t…
Role of dimension-eight operators in an EFT for the 2HDM
Sally Dawson, Duarte Fontes, Samuel Homiller +1
The Standard Model effective field theory (SMEFT) is the tool of choice for studying deviations of Higgs couplings from the Standard Model predictions. The SMEFT is an expansion in…
Flavorful Electroweak Precision Observables in the Standard Model Effective Field Theory

Electroweak precision observables (EWPO) measured at the W and Z poles provide stringent limits on possible beyond the Standard Model physics scenarios. In an effective field theor…
Truncation, validity, uncertainties
Ilaria Brivio, Sally Dawson, Jorge de Blas +19
The truncation of the standard-model effective field theory, its validity and the associated uncertainties have been discussed in meetings of the LHC EFT WG. Proposals were made by…
Electroweak input parameters
Ilaria Brivio, Sally Dawson, Jorge de Blas +7
Different sets of electroweak input parameters are discussed for SMEFT predictions at the LHC. The {Gmu,mZ,mW} one is presently recommended.
The Impact of Dimension-8 SMEFT Contributions: A Case Study
Sally Dawson, Samuel Homiller, Matthew Sullivan
The use of the SMEFT Lagrangian to quantify possible Beyond the Standard Model (BSM) effects is standard in LHC and future collider studies. One of the usual assumptions is to trun…
New Physics Through Drell Yan SMEFT Measurements at NLO
Sally Dawson, Pier Paolo Giardino
Drell Yan production is a sensitive probe of new physics and as such has been calculated to high order in both the electroweak and QCD sectors of the Standard Model, allowing for p…
Uncovering the High Scale Higgs Singlet Model
Sally Dawson, Pier Paolo Giardino, Samuel Homiller
The scalar singlet model extends the Standard Model with the addition of a new gauge singlet scalar. We re-examine the limits on the new scalar from oblique parameter fits and from…

D. Marzocca, F. Riva, J. Criado +9
Effective Field Theories (EFTs) capture effects from heavy dynamics at low energy and represent an essential ingredient in the context of Standard Model (SM) precision tests. This…
