Closer look at postdecay tt entanglement

Publicated to:PHYSICAL REVIEW D. 109 (9): 096027- - 2024-05-20 109(9), DOI: 10.1103/PhysRevD.109.096027

Abstract

Top pair production is ideally suited to observe postdecay entanglement, thus providing a novel test of quantum mechanics. We provide top polarized decay amplitudes that can be used to compute semianalytical predictions and, in particular, to better understand why the postdecay entanglement arises. We obtain predictions for the LHC, identifying general phase space regions where experimental measurements of tW entanglement are feasible. We also give predictions for polarized e + e - collisions, focusing on the possibility that the postdecay tW entanglement is larger than the tt one.
