Einstein-Podolsky-Rosen-Bohm experiment with massive particles as a test of relativistic center-of-mass position operator

Marek Czachor

The nonrelativistic singlet state average $⟨\psi |\vec{a}\cdot \vec{\sigma }\otimes \vec{b}\cdot \vec{\sigma }|\psi ⟩=-\vec{a}\cdot \vec{b}$ can be relativistically generalized if one define…
