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 ...

Renormalisation group evolution effects on global SMEFT analyses [PDF]
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 ...

On the non-minimal character of the SMEFT [PDF]
Physics Letters B, 2017 When integrating out unknown new physics sectors, what is the minimal character of the Standard Model Effective Field Theory (SMEFT) that can result? In this paper we focus on a particular aspect of this question: “How can one obtain only one dimension ...

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.

Future DUNE constraints on EFT
Journal of High Energy Physics, 2018 In the near future, fundamental interactions at high-energy scales may be most efficiently studied via precision measurements at low energies. A universal language to assemble and interpret precision measurements is the so-called SMEFT, which is an ...

Low-energy effective field theory below the electroweak scale: operators and matching
Journal of High Energy Physics, 2018 The gauge-invariant operators up to dimension six in the low-energy effective field theory below the electroweak scale are classified. There are 70 Hermitian dimension-five and 3631 Hermitian dimension-six operators that conserve baryon and lepton number,

Two‐to‐Two Processes at an Electron‐Muon Collider
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Based on a recent proposal to build an electron‐muon collider, we study two‐to‐two production processes e−μ+⟶ff¯, γγ that originate from dimension 6 and 8 operators. We compare the sensitivity to those effective couplings obtained at the collider with that of low energy measurements of μ⟶eγ, μ⟶ee¯e, and μ⟶e conversion that have recently been reported ...
