Probing the flavour-blind SMEFT: EFT validity and the interplay of energy scales
Journal of High Energy PhysicsThe Standard Model Effective Field Theory (SMEFT) offers a systematic approach to study potential deviations from the Standard Model (SM) through higher-dimensional operators that encapsulate new physics effects.

SMEFT at NNLO+PS: Vh production
Journal of High Energy PhysicsIn the context of the Standard Model effective field theory (SMEFT) the next-to-next-to-leading (NNLO) QCD corrections to the Higgsstrahlungs (Vh) processes in hadronic collisions are calculated and matched to a parton shower (PS).

Reactor neutrino oscillations as constraints on effective field theory
Journal of High Energy Physics, 2019 We study constraints on the Standard Model Effective Field Theory (SMEFT) from neutrino oscillations in short-baseline reactor experiments. We calculate the survival probability of reactor antineutrinos at the leading order in the SMEFT expansion, that ...

Electroweak input schemes and universal corrections in SMEFT
Journal of High Energy Physics, 2023 The choice of an electroweak (EW) input scheme is an important component of perturbative calculations in Standard Model Effective Field Theory (SMEFT).

Renormalisation group evolution effects on global SMEFT analyses
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 ...

, 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 $Λ$. Usually, in order to perform calculations, gauge independent field re-definitions consistent with the symmetries of the theory are then used to redefine the fields.
