Working on SMEFT in top quark sector. More precisely, I am looking for observables sensitive to the SMEFT effects in processes involving top quarks, especially the production of four tops.

My current work consist in the automation of the one-loop renormalization of the electroweak sector in the SMEFT. I am also interested in gauge invariance in both the SM and GR and in non-local effects.

Research statement
I am working on Effective Field Theory (EFT) at colliders mainly in top and electroweak sector. Recently, I have been focusing on the interplay between PDF and EFT fits and on the computation of NLO QCD corrections for the SMEFT.
I am the author of NLOCT and one of the FeynRules authors.
I am also investigating how the photon polarisation in cosmic rays can be used to probe BSM physics.

The project aims at simultaneously fit PDF and the SMEFT. The first step was the introduction of 4 four-fermion operators in the DIS fit. The next steps are the inclusion of other relevant operators and to increased the data sets used.
External collaborators: Maria Ubiali, Stephano Carrazza, Juan Rojo, Shayan Iranipour.
