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…
