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…
