Extracting a Toponium Signal at the LHC with Spin and Quantum Information Tools
Laura Antozzi, Esteban Chalbaud, Frédéric Déliot +6
We investigate near-threshold top-antitop production at the LHC, focusing on the impact of toponium formation on spin correlations and quantum information properties of the final s…

Emergent symmetry in a two-Higgs-doublet model from quantum information and nonstabiliserness
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
Studies of scattering processes in scalar models with two Higgs doublets have recently hinted at a connection between the absence of flavour-space entanglement in scatte…
