Indirect constraints on top quark operators from a global SMEFT analysis [PDF]
Journal of High Energy Physics, 2023 We perform a model-independent analysis of top-philic New Physics scenarios, under the assumption that only effective operators involving top quarks are generated at tree level.

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 ...

Uniting low-energy semileptonic and hadronic anomalies within SMEFT [PDF]
Journal of High Energy PhysicsTwo categories of four-fermion SMEFT operators are semileptonic (two quarks and two leptons) and hadronic (four quarks). At tree level, an operator of a given category contributes only to processes of the same category.

Higgs boson production at large transverse momentum within SMEFT: analytical results [PDF]
, 2018 We consider Higgs boson production through gluon fusion at large transverse momentum in hadronic collisions. We present the analytic expressions of the relevant one-loop QCD amplitudes including the effects of the complete set of dimension-six operators.

EWPD in the SMEFT to dimension eight [PDF]
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 ...

Energy-enhanced dimension eight SMEFT effects in VBF Higgs production [PDF]
Journal of High Energy PhysicsWe study Higgs boson production via vector boson fusion at the LHC, focusing on the process pp → H + jj and capturing the leading energy-enhanced contributions within the Standard Model Effective Field Theory (SMEFT) up to order 1/Λ4.

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 ...

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
