We study the discovery potential of down type iso-singlet quarks, D, predicted by the E6 GUT model in the pp→DDˉ→ZZddˉ→ℓ+ℓ−ℓ+ℓ−ddˉ channel at the HL-LHC and FCC-hh colliders. The analysis is performed using a high level analysis description language and its runtime interpreter. The study shows that, using solely this channel, HL-LHC can discover D quarks up to a mass of 710 GeV whereas FCC-hh up to 2430 GeV with data collected in their complete run periods.
