Renormalization group equations for the SMEFT operators up to dimension seven [PDF]
Journal of High Energy Physics, 2023 In this paper, we propose a Green’s basis and also a new physical basis for dimension-seven (dim-7) operators, which are suitable for the matching of ultraviolet models onto the Standard Model effective field theory (SMEFT) and the deviation of ...

Mapping the SMEFT to discoverable models [PDF]
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 ...

Journal of High Energy Physics, 2021 There are two canonical approaches to treating the Standard Model as an Effective Field Theory (EFT): Standard Model EFT (SMEFT), expressed in the electroweak symmetric phase utilizing the Higgs doublet, and Higgs EFT (HEFT), expressed in the broken ...

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 ...

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

Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing [PDF]
Journal of High Energy PhysicsWe derive the dimension-8 standard-model effective theory (SMEFT) contact terms relevant for vector-pair production at the LHC and lepton colliders.

Renormalisation group evolution effects on global SMEFT analyses [PDF]
Journal of High Energy PhysicsGlobal analyses in the Standard Model Effective Field Theory (SMEFT) framework serve as a tool to probe potential directions of new physics. To break degeneracies between the Wilson coefficients of the SMEFT, it is essential to combine observables from ...

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).

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).
