Quantum state tomography, entanglement detection and Bell violation prospects in weak decays of massive particles
Rachel Ashby-Pickering, Alan J. Barr, Agnieszka Wierzchucka
A rather general method for determining the spin density matrix of a multi-particle system from angular decay data is presented. The method is based on a Bloch parameterisation of…

Bell-type inequalities for systems of relativistic vector bosons
Alan J. Barr, Pawel Caban, Jakub Rembieliński
We perform a detailed analysis of the possible violation of various Bell-type inequalities for systems of vector boson-antiboson pairs. Considering the general case of an overall s…
