Constraining top-quark couplings combining top-quark and decay observables
Stefan Bißmann, Johannes Erdmann, Cornelius Grunwald +2
We present a first, consistent combination of measurements from top-quark and physics to constrain top-quark properties within the Standard Model Effective Field Theory (SMEFT)…
Study of interference effects in the search for flavour-changing neutral current interactions involving the top quark and a photon or a boson at the LHC
Maura Barros, Nuno Filipe Castro, Johannes Erdmann +4
Flavour-changing neutral-current interactions of the top quark can be searched for in top-quark pair production with one top quark decaying to an up-type quark and a neutral boson,…
From the Bottom to the Top -- Reconstruction of Events with Deep Learning
Johannes Erdmann, Tim Kallage, Kevin Kröninger +1
The reconstruction of top-quark pair-production () events is a prerequisite for many top-quark measurements. We use a deep neural network, trained with Monte-Carlo simula…
Overview of searches for single production of vector-like top and bottom quarks with the ATLAS experiment at 13 TeV
Johannes Erdmann
Vector-like quarks (VLQ) that couple preferentially to third-generation Standard Model (SM) quarks are a well-motivated extension of the SM, which could solve in particular the hie…
