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.

smelli – the SMEFT Likelihood [PDF]
, 2021 I present the Python package smelli that implements a global likelihood function in the space of dimension-six Wilson coefficients in the Standard Model Effective Field Theory (SMEFT).

Loop counting matters in SMEFT [PDF]
, 2022 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).

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 ...

On the Impact of the LHC Run 2 Data on General Composite Higgs Scenarios
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 We study the impact of Run 2 LHC data on general composite Higgs scenarios, where nonlinear effects, mixing with additional scalars, and new fermionic degrees of freedom could simultaneously contribute to the modification of Higgs properties. We obtain new experimental limits on the scale of compositeness, the mixing with singlets and doublets with the

Non-standard interactions in SMEFT confronted with terrestrial neutrino experiments
Journal of High Energy Physics, 2021 The Standard Model Effective Field Theory (SMEFT) provides a systematic and model-independent framework to study neutrino non-standard interactions (NSIs).

, 2023 This document contains lectures on SMEFT, which is an effective field theory of the degrees of freedom of the Standard Model. The material is at a basic, introductory level, without assuming any prior knowledge of effective field theory techniques.

Froggatt-Nielsen meets the SMEFT [PDF]
We study the matching of Froggatt-Nielsen theories of flavour onto the Standard Model Effective Field Theory (SMEFT), upon integrating out a heavy Beyond-the-Standard-Model (BSM) scalar ‘flavon’ whose vacuum expectation value breaks an Abelian flavour ...

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 ...
