Diboson production in the SMEFT at dimension-8
Hesham El Faham, Giuseppe Ventura, Eleni Vryonidou
We present a comprehensive analysis of dimension-8 and dimension-6 effects in fully leptonic and production at the Large Hadron Collider (LHC) within the Standard Model (…

Two-loop renormalisation of quark and gluon fields in the SMEFT in the on-shell scheme
Claude Duhr, Giuseppe Ventura, Eleni Vryonidou
We compute the contributions of CP-conserving dimension-six SMEFT operators to the two-loop renormalisation constants of quark and gluon fields in the on-shell scheme. Specifically…

Constraining four-heavy-quark operators with top-quark, Higgs, and electroweak precision data
Stefano Di Noi, Hesham El Faham, Ramona Gröber +2
We establish constraints on the dimension-six four-heavy-quark operators in the Standard Model Effective Field Theory (SMEFT) by synthesising LHC measurements of top-quark and sing…
