Toponium effects on quantum steering and Bell nonlocality of top quarks
J. A. Aguilar-Saavedra, S. RodrÃguez-BenÃtez
We investigate quantum steering and Bell nonlocality in top-quark pair production at the LHC near threshold. The toponium contribution strengthens the spin-singlet component and su…

Understanding Bell locality tests at colliders
J. A. Aguilar-Saavedra, J. A. Casas, J. M. Moreno
For decades, it has been known that local hidden variable theories cannot be disproved by collider experiments involving decaying particles. However, if these theories satisfy a sm…

Quantum tomography of beyond leading order
J. A. Aguilar-Saavedra, Pier Paolo Giardino
We revisit quantum tomography of and in the presence of higher-order corrections. We verify that neither the use of an effective spin analysing power (only fo…
