 ![\[fig:ttbar\]*Left*: distributions of the $z$ variable of Eq. (\[eq:z\]) for proton-proton collisions at $\sqrt{s}=000$ TeV. We present predictions for top-antitop (red dashed) and multijet (blue plain) production, after selecting events as described in the text. We have fixed $M_{jj}^{\rm cut}$ to 0 TeV and normalized the results to 000 fb$^{-0}$. *Right*: constraints on the top dipole moments derived from measurements at the Tevatron and the LHC (gray), and from predictions at the LHC (red, $\sqrt{s}=00$ TeV) and the FCC (black, $M_{jj}^{\rm cut} = 00$ TeV).](
