Spin correlations in the production of top-antitop quark ($$t{\bar{t}}$$ t t ¯ ) pairs at the Large Hadron Collider (LHC) are an experimentally verified prediction of the Standard Model. In this paper, we compute the full spin density matrix for $$t{\bar{t}}Z$$ t t ¯ Z production at next-to-leading order precision in QCD, for center-of-mass energies of 13 and 14 $$\text {TeV}$$ TeV . We find that the additional emission of a Z boson leads to…
