European Physical Journal C: Particles and Fields, 2023 This work is based on a bottom-up approach to the standard-model effective field theory (SMEFT), resulting in an equiprobable space of Wilson coefficients.

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 ...

SMEFT atlas of ∆F = 2 transitions [PDF]
Journal of High Energy Physics, 2020 We present a model-independent anatomy of the ∆F = 2 transitions K 0 − K ¯ 0 $$ {\overline{K}}^0 $$ , B s,d − B ¯ s , d $$ {\overline{B}}_{s,d} $$ and D 0 − D ¯ 0 $$ {\overline{D}}^0 $$ in the context of the Standard Model Effective Field Theory (SMEFT).

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).

Towards the ultimate differential SMEFT analysis [PDF]
Journal of High Energy Physics, 2020 Abstract We obtain SMEFT bounds using an approach that utilises the complete multi-dimensional differential information of a process. This approach is based on the fact that at a given EFT order, the full angular distribution in the most important electroweak processes can be expressed as a sum of a fixed number of basis functions.

Loop counting matters in SMEFT
SciPost Physics, 2023 We show that, in addition to the counting of canonical dimensions, a counting of loop orders is necessary to fully specify the power counting of Standard Model Effective Field Theory (SMEFT).

ALP — SMEFT interference [PDF]
Journal of High Energy Physics, 2021 Abstract The Standard Model Effective Field Theory (SMEFT) offers a powerful theoretical framework for parameterizing the low-energy effects of heavy new particles with masses far above the scale of electroweak symmetry breaking. Additional light degrees of freedom extend the effective theory.
