An EFT study of the pp → t̄ t Z(ll) h(bb) process at the FCC-hh

We carry out an Effective Field Theory (EFT) study of the pp → t̄ t Zh process in the 4b + 3 + ≥ 2j + ET final state. This process can uniquely probe the t̄ t Zh couplings arising from higher dimensional EFT operators and can also provide bounds on t̄ t Z coupling deviations. We highlight the importance of the proposed proton-proton Future Circular Collider (FCC-$hh$) to study this process and then perform a complete collider analysis by examining the relevant background processes. This allows us to determine the FCC-$hh$ sensitivity to probe anomalous t̄ t Zh couplings.
