Probing the coupling of axions to tops and gluons with LHC measurements
Jon Butterworth, Matthew Cullingworth, Joseph Egan +3
We study axion-like particles (ALPs) whose dominant interactions are with gluons and third-generation quarks, and whose couplings to light Standard Model (SM) particles arise at on…
Data-driven discovery strategy for standard model effective field theory searches
Martin Hirsch, Luca Mantani, Veronica Sanz
We present a novel strategy to uncover indirect signs of new physics in collider data using the Standard Model Effective Field Theory (SMEFT) framework, offering notably improved s…
Probing the flavour-blind SMEFT: EFT validity and the interplay of energy scales
Luca Mantani, Veronica Sanz
The Standard Model Effective Field Theory (SMEFT) offers a systematic approach to study potential deviations from the Standard Model (SM) through higher-dimensional operators that…
Faking ZZZ vertices at the LHC
Ricardo Cepedello, Fabian Esser, Martin Hirsch +1
Searches for anomalous neutral triple gauge boson couplings (NTGCs) provide important tests for the gauge structure of the standard model. At the LHC, NTGCs are searched for via th…
