Abstract This paper explores the physics reach of the proton–proton future circular collider (FCC-hh) and of the High-Energy LHC (HE-LHC) for searches of new particles produced in the s-channel and decaying to two high-energy leptons, jets (non-tops), tops or W/Z bosons. We discuss the expected discovery potential and exclusion limits for benchmark models predicting new massive particles that result in resonant structures in the invariant mass spectrum. We also present a detailed study of the HE-LHC potential to discriminate among different models, for a $$Z^{\prime }$$ Z′ that could be discovered by the end of high-luminosity LHC (HL-LHC).
