Query: On two-body and three-body spin correlations in leptonic $t\bar{t}Z$
  production and anomalous couplings at the LHC   We study the anomalous $t\bar{t}Z$ couplings in the $t\bar{t}Z$ production in
$4l+2b+MET$ final state at the $13$ TeV LHC. We use the polarizations of top
quarks and $Z$ boson, two-body and three-body spin correlations among the top
quarks and $Z$ boson, and the cross section to probe the anomalous couplings
and estimate a limit on the couplings of the effective vertex as well as the
effective operators for a set of luminosities $150$ fb$^{-1}$, $300$ fb$^{-1}$,
and $3000$ fb$^{-1}$. The polarizations and the spin correlations are found to
be helpful on top of the cross section to better constrain the anomalous
couplings.
