Effective Quantum Field Theory and SMEFT
Anisha, Anke Biekötter, Matthias König
We introduce the basics of Effective Field Theories, using the Standard Model Effective Field Theory as our central example. The first part of this chapter gives a pedagogical intr…
ALP-ine quests at the LHC: hunting axion-like particles via peaks and dips in production
Afiq Anuar, Anke Biekötter, Thomas Biekötter +5
We present an analysis of the sensitivity of current and future LHC searches for new spin-0 particles in top-anti-top-quark () final states, focusing on generic axion-lik…
Using the effective weak mixing angle as an input parameter in SMEFT
Anke Biekötter, Benjamin D. Pecjak, Tommy Smith
We implement electroweak renormalisation schemes involving the effective weak mixing angle to NLO in Standard Model Effective Field Theory (SMEFT). After developing the necessary t…
A global analysis of the SMEFT under the minimal MFV assumption
Riccardo Bartocci, Anke Biekötter, Tobias Hurth
We present comprehensive global fits of the SMEFT under the minimal flavour violation (MFV) hypothesis, i.e. assuming that only the flavour-symmetric and CP-inva…
A global analysis of axion-like particle interactions using SMEFT fits
Anke Biekötter, Javier Fuentes-Martín, Anne Mareike Galda +1
In the presence of an axion or axion-like particle (ALP) that couples to the Standard Model via dimension-five interactions, dimension-six SMEFT interactions are generated via reno…
Electroweak input schemes and universal corrections in SMEFT
Anke Biekötter, Benjamin D. Pecjak, Darren J. Scott +1
The choice of an electroweak (EW) input scheme is an important component of perturbative calculations in Standard Model Effective Field Theory (SMEFT). In this paper we perform a s…
New Higgs decays to axion-like particles
Anke Biekötter, Mikael Chala, Michael Spannowsky
We investigate the interactions of a light scalar with the Higgs boson and second-generation fermions, which trigger new rare decays of the Higgs boson into , , and…
Effective limits on single scalar extensions in the light of recent LHC data
Anisha, Supratim Das Bakshi, Shankha Banerjee +4
In this paper, we work with 16 different single scalar particle extensions of the Standard Model. We present the sets of dimension-6 effective operators and the associated Wilson c…
Potential and limitations of machine-learning approaches to inclusive determinations
Anke Biekötter, Ka Wang Kwok, Benjamin D. Pecjak
The determination of in inclusive semileptonic decays will be among the pivotal tasks of Belle II. In this paper we study the potential and limitation…
Complementarity of Resonant Scalar, Vector-Like Quark and Superpartner Searches in Elucidating New Phenomena
Anke Biekötter, JoAnne L. Hewett, Jong Soo Kim +5
The elucidation of the nature of new phenomena requires a multi-pronged approach to understand the essential physics that underlies it. As an example, we study the simplified model…
Pushing Higgs Effective Theory over the Edge
Anke Biekötter, Johann Brehmer, Tilman Plehn
Based on a vector triplet model we study a possible failure of dimension-6 operators in describing LHC Higgs kinematics. First, we illustrate that including dimension-6 contributio…
Vices and Virtues of Higgs EFTs at Large Energy
Anke Biekoetter, Alexander Knochel, Michael Kraemer +2
We study constraints on new physics from Higgs production at the LHC in the context of an effective field theory (EFT), focusing on Higgs searches in () associated prod…
