${{\mathit t}}$ ${{\overline{\mathit t}}}$ ${{\mathit Z}}$ $\rightarrow$ 3,4 ${{\mathit \ell}}$ + $\not E_T$ + jets

¹ Based on 19.5 fb${}^{-1}$ of data. The result is consistent with the SM prediction of ${\mathit \sigma (}$ ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit Z}}{)}$ = $197$ ${}^{+22}_{-25}$ fb.
