SMEFT Treatment for the Higgs Boson with the ATLAS Experiment

, 2022
The Run-2 of the LHC sets the stage to scrutinize the Standard Model Effective Field Theory (SMEFT). SMEFT provides a theoretically well-defined framework to consistently interpret measurements of different processes, to search for indirect effects of ...

A framework for simultaneous fit of QCD and BSM parameters with xFitter

European Physical Journal C: Particles and Fields
An extension of the xFitter open-source program for QCD analyses is presented, allowing for a polynomial parameterization of the dependence of physical observables on theoretical parameters.

On the non-minimal character of the SMEFT

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 ...

The geometric SMEFT [PDF]

, 2022
Effective field theories, like the Standard Model Effective Field Theory (SMEFT), are defined by a chosen field content and a set of symmetries, up to a cut off scale $\Lambda$.

Electroweak input schemes and universal corrections in SMEFT

, 2023
The choice of an electroweak (EW) input scheme is an important component of perturbative calculations in Standard Model Effective Field Theory (SMEFT).

Constraining SMEFT operators with associated hγ production in weak boson fusion [PDF]

, 2021
We consider the associated production of a Higgs boson and a photon in weak boson fusion in the Standard Model (SM) and the Standard Model Effective Field Theory (SMEFT), with the Higgs boson decaying to a pair of bottom quarks. Analysing events in a cut-

Connecting t-channel dark matter models to the Standard Model Effective Field Theory

Journal of High Energy Physics
We investigate the connection between simplified dark matter models featuring a t-channel scalar mediator and the Standard Model Effective Field Theory (SMEFT).

Higgs production from anomalous gluon dynamics

Journal of High Energy Physics
We present a two-loop analysis of the contributions to Higgs production via gluon-gluon fusion arising from the triple-gluon operator in the Standard Model effective field theory (SMEFT).

Reactor neutrino oscillations as constraints on effective field theory

Journal of High Energy Physics, 2019
We study constraints on the Standard Model Effective Field Theory (SMEFT) from neutrino oscillations in short-baseline reactor experiments. We calculate the survival probability of reactor antineutrinos at the leading order in the SMEFT expansion, that ...

Higgs decay to fermion pairs at NLO in SMEFT [PDF]

, 2020
The calculation of next-to-leading order (NLO) perturbative corrections at fixed operator dimension in Standard Model Effective Field Theory (SMEFT) has been a topic of much recent interest.
