My research explores four-heavy-quark operators in the Standard Model Effective Field Theory (SMEFT), with a focus on the loop-level effects of third-generation quarks. I aim to extend current studies beyond top-quark pair production to include bottom-quark, single-top, and electroweak processes. By tackling evanescent operators, counter-terms, and implementing precise predictions in Monte Carlo tools, I work toward global SMEFT fits that reveal collider sensitivities and potential signs of new physics.

(member since October 2024)
I am interested in the fundamental aspects of field theories, as well as the way we use theory to make predictions. I intend to better understand how we can use EFTs to study the fingerprints that UV physics necessarily leaves at accessible energy scales. In practice I am working on improving the way we compute amplitudes and study their analytic structure.

Scattering amplitude techniques for effective theories
Waël Aoun, Gauthier Durieux
We use scattering amplitude techniques to gain further insight about effective theories and that of the standard model in particular, together with its phenomenology.

Standard-model effective theory phenomenology
Murad Ali, Gauthier Durieux
We study the impact of effective-field-theory deformation of the standard model on present and future collider measurements, exploring observable sensitivities and complementarities, providing and studying higher-order corrections.
