Differential measurements at large Q2 at the FCC-hh

In this note, we document the projected precision for differential \ttbar production in the fully hadronic final state, WW production in the $\rm e\mu$ final state, and \ftop (four top) production in the fully leptonic final state. We also discuss the sensitivity for observing and measuring four top production at the FCC-hh. We show that this process can be measured with 4\% precision at the FCC-hh using the very rare $\rm e^{\pm} e^{\pm} \mu^{\mp} \mu^{\mp}$ decay.
