# Measurement of Bell-type inequalities and quantum entanglement from $\Lambda$-hyperon spin correlations at high energy colliders

@inproceedings{Gong2021MeasurementOB, title={Measurement of Bell-type inequalities and quantum entanglement from \$\Lambda\$-hyperon spin correlations at high energy colliders}, author={Wenjie Gong and Ganesh Parida and Zhoudunming Tu and Raju Venugopalan}, year={2021} }

Spin correlations of Λ-hyperons embedded in the QCD strings formed in high-energy collider experiments provide unique insight into their locality and entanglement features. We show from general considerations that while the Clauser-Horne-Shimony-Holt inequality is less stringent for such states, they provide a benchmark for quantum-to-classical transitions induced by varying i) the associated hadron multiplicity, ii) the spin of nucleons, iii) the separation in rapidity between pairs, and iv…

It is shown how the measurement of a single observable can provide a test of the violation of a Bell inequality at the 98% C.L. with the statistical uncertainty of the data already collected at the Large Hadron Collider, and at the 99.99% L with the higher luminosity of the next run.
