Helicity correlations of vector bosons

TL;DR

This paper analyzes helicity and polarization correlations of relativistic vector bosons, demonstrating violations of Bell inequalities and their dependence on particle momentum, with implications for quantum entanglement in high-energy physics.

Contribution

It provides a detailed calculation of helicity and polarization correlations for relativistic vector bosons, revealing their violation of Bell inequalities and the influence of particle momentum.

Findings

Polarization correlation functions violate Bell inequalities.

Violation magnitude increases with particle momentum.

Massless limit matches scalar two-photon state correlations.

Abstract

We calculate the helicity and polarization correlation functions in the Einstein-Podolsky-Rosen-type experiments with relativistic vector bosons. We show that the linear polarization correlation function in the appriopriately chosen state in the massless limit is the same as the correlation function in the scalar two-photon state. We show also that the polarization correlation function violate the Clauser-Horne-Shimony-Holt inequality and that the degree of this violation can increase with the particle momentum.
