Testing the CKM unitarity at high energy via the production at the LHC and future colliders
E. Gabrielli, L. Marzola, K. Müürsepp
We propose a novel test to assess the unitarity of the Cabibbo-Kobayashi-Maskawa matrix, , at present and future collider experiments. Our strategy makes use of the $W…
Measuring CP violation using quantum state tomography
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
We investigate direct CP violation in neutral meson decays by reconstructing the associated density matrices and measuring their difference using the trace distance. Our results co…
Quantum pions
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
We show that two- and three-pion states produced in the decay of neutral kaons are contextual, entangled, and Bell nonlocal in isospin space. By reinterpreting the experimental val…
Tests of quantum contextuality in particle physics
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
Quantum contextuality refers to the impossibility of assigning a predefined, intrinsic value to a physical property of a system independently of the context in which the property i…
Quantum contextuality of spin-1 massive particles
M. Fabbrichesi, R. Floreanini, E. Gabrielli +1
Contextuality is a fundamental property of quantum mechanics. Contrary to entanglement, which can only exist in composite systems, contextuality is also present for single entities…
