The Higgs width in the SMEFT [PDF]
Journal of High Energy Physics, 2019 Abstract We calculate the total and partial inclusive Higgs widths at leading order in the Standard Model Effective Field Theory (SMEFT). We report results incorporating SMEFT corrections for two and four body Higgs decays through vector currents in this limit. The narrow width approximation is avoided and all phase space integrals

The CKM parameters in the SMEFT [PDF]
Journal of High Energy Physics, 2019 Abstract The extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix from flavour observables can be affected by physics beyond the Standard Model (SM). We provide a general roadmap to take this into account, which we apply to the case of the Standard Model Effective Field Theory (SMEFT).

A package for renormalization group running in the SMEFT with sterile neutrinos [PDF]
European Physical Journal C: Particles and FieldsSterile neutrinos are well-motivated beyond the Standard Model (BSM) particles. The Standard Model Effective Field Theory (SMEFT) augmented with these new fields is known as the $$\nu $$ ν SMEFT.

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).

Improving the global SMEFT picture with bounds on neutrino NSI [PDF]
Journal of High Energy PhysicsWe analyze how neutrino oscillation and coherent elastic neutrino-nucleus scattering data impact the global SMEFT fit. We first review the mapping between the SMEFT parameters and the so-called NSI framework, commonly considered in the neutrino ...

Threshold corrections in SMEFT
Journal of High Energy PhysicsThreshold corrections provide a universal link between experimentally measured broken-phase parameters and MS ¯ $$ \overline{\mathrm{MS}} $$ renormalised symmetric-phase parameters used in SMEFT renormalisation-group (RG) analyses and matching to new ...

Triple-gauge couplings in LHC diboson production: a SMEFT view from every angle
Journal of High Energy PhysicsThis study explores fully leptonic WZ and WW production at the LHC within the SMEFT framework at NLO in QCD, focusing on both CP-even and CP-odd triple-gauge-coupling dimension-six operators.

Loop counting matters in SMEFT [PDF]
, 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).
