Quantum detection of CP violation in the system: tomography
Priyanka Lamba, Fabio Maltoni, Olimpia Miniati +1
We develop a quantum-tomographic framework for determining whether possible CP-odd effects in events originate in production, in decay, or in both. In the narrow-width ap…
Quantum detection of CP violation in the system: production
Priyanka Lamba, Fabio Maltoni, Olimpia Miniati +1
We investigate how possible new CP-violating top-quark interactions are encoded in the quantum state of a produced pair. We derive analytic expressions for the production…
Sensitivity to top-quark couplings in diboson production at lepton colliders
Eugenia Celada, Víctor Miralles, Eleni Vryonidou
We study the next-to-leading order electroweak corrections to from dimension-six two-fermion top-quark operators in the Standard Model Effective Field T…
Two-loop renormalisation of the quark fields in the presence of four-fermion SMEFT operators
Claude Duhr, Giuseppe Ventura, Eleni Vryonidou
We compute the contributions of the dimension-6 SMEFT operators involving four third-generation quarks to the two-loop renormalisation of the quark fields and masses. We perform th…
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…
Top and Higgs: Recent Theory developments
Eleni Vryonidou
I review recent theory developments in the computation of Higgs production in association with top quarks, as well as the modelling of the corresponding backgrounds. In addition to…
Top and Electroweak bosons and Higgs
Eleni Vryonidou
I review recent progress in the computation of processes involving top quarks in the framework of Standard Model Effective Theory at NLO in QCD. In particular I discuss the impact…
