, 2022 Effective field theories, like the Standard Model Effective Field Theory (SMEFT), are defined by a chosen field content and a set of symmetries, up to a cut off scale $\Lambda$.

From models to SMEFT and back? [PDF]
SciPost Physics, 2022 We present a global analysis of the Higgs and electroweak sector, in the SMEFT framework and matched to a UV-completion. As the UV-model we use the triplet extension of the electroweak gauge sector.

Uncovering the root of LEFT in SMEFT [PDF]
Europhysics Letters, 2022 At energies below the electroweak scale, baryon number B and lepton number L violating processes are of significant importance in identifying the nature of UV extensions of the Standard Model.

Flavourful SMEFT likelihood for Higgs and electroweak data
Journal of High Energy Physics, 2020 We perform an updated fit to LHC Higgs data and LEP electroweak precision tests in the framework of the Standard Model Effective Field Theory (SMEFT). We assume a generic structure of the SMEFT operators without imposing any flavour symmetries.

, 2020 In spite of the non-observation of any new resonances after the discovery of the Standard Model (SM) Higgs-like particle, which announces the success of the SM, we have enough reason to believe the existence of theories beyond it (BSM), with the SM as a ...

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 ...

EWPD in the SMEFT to dimension eight
Journal of High Energy Physics, 2021 We calculate the O H † H 2 / Λ 4 $$ \mathcal{O}\left({\left\langle {H}^{\dagger }H\right\rangle}^2/{\Lambda}^4\right) $$ corrections to LEP electroweak precision data using the geometric formulation of the Standard Model Effective Field Theory (SMEFT ...

, 2020 In this work we address three questions: can we successfully describe (observed) deviations from the standard model in the SMEFT language? Can we learn something about the underlying, beyond the standard model, physics using the SMEFT language?

Renormalisation group effects on SMEFT interpretations of LHC data
Journal of High Energy Physics, 2023 We explore the impact of Renormalisation Group (RG) effects in the Standard Model Effective Field Theory (SMEFT) interpretations of LHC measurements.
