On the non-minimal character of the SMEFT [PDF]
Physics Letters B, 2017 When integrating out unknown new physics sectors, what is the minimal character of the Standard Model Effective Field Theory (SMEFT) that can result? In this paper we focus on a particular aspect of this question: “How can one obtain only one dimension ...

SIMUnet: an open-source tool for simultaneous global fits of EFT Wilson coefficients and PDFs [PDF]
European Physical Journal C: Particles and FieldsWe present the open-source SIMUnet code, designed to fit Standard Model Effective Field Theory (SMEFT) Wilson coefficient alongside Parton Distribution Functions (PDFs) of the proton. SIMUnet can perform SMEFT global fits, as well as simultaneous fits of

Future DUNE constraints on EFT
Journal of High Energy Physics, 2018 In the near future, fundamental interactions at high-energy scales may be most efficiently studied via precision measurements at low energies. A universal language to assemble and interpret precision measurements is the so-called SMEFT, which is an ...

Higgs decays to two leptons and a photon beyond leading order in the SMEFT
SciPost Physics, 2022 We present the three-body decay of the Higgs boson into two leptons and a photon to dimension-eight in the Standard Model Effective Field Theory (SMEFT).

Mapping the SMEFT to discoverable models
Journal of High Energy Physics, 2022 The matching of specific new physics scenarios onto the SMEFT framework is a well-understood procedure. The inverse problem, the matching of the SMEFT to UV scenarios, is more difficult and requires the development of new methods to perform a systematic ...

SMEFT as a slice of HEFT’s parameter space [PDF]
EPJ Web of Conferences, 2022 The Standard Model Effective Field Theory (SMEFT) is the parametrization chosen to interpret many modern measurements. We have recently discussed, building on the work of other groups, that its overall framework can be experimentally tested, beyond ...

Non-standard interactions in SMEFT confronted with terrestrial neutrino experiments
Journal of High Energy Physics, 2021 The Standard Model Effective Field Theory (SMEFT) provides a systematic and model-independent framework to study neutrino non-standard interactions (NSIs).

Leptoquarks meet $\varepsilon'/\varepsilon$ and rare Kaon processes [PDF]
, 2016 We analyse for the first time the CP violating ratio $\varepsilon'/\varepsilon$ in $K\to \pi\pi$ decays in leptoquark (LQ) models. Assuming a mass gap to the electroweak (EW) scale, the main mechanism for LQs to contribute to $\varepsilon'/\varepsilon ...

The Standard Model as an Effective Field Theory [PDF]
, 2018 Projecting measurements of the interactions of the known Standard Model (SM) states into an effective field theory (EFT) framework is an important goal of the LHC physics program.
