Abstract

We investigated the quantum entanglement phenomenon of the top-antitop (tt̅) quarks produced from proton-proton collision at √s = 100 TeV. We used a Monte-Carlo generator, MadGraph, to generate simulated collisions at truth-level. We then used Rivet for the analysis of the data generated from the simulation. The spin-correlation coefficient D was used as a measure for entanglement of the (tt̅) pair. We were able to see that there is higher likelihood for entanglement in lower mass invariant of (tt̅) quark pair wherein the threshold starts to appear from the low-end near the 500 GeV mark.
