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…
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…
Sensitivity to top-quark couplings in diboson production at lepton colliders
Eugenia Celada, VÃctor 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 (…
