The physics reach and feasibility of the Future Circular Collider (FCC) with center of mass energies up to 100 TeV and unprecedented luminosity is currently under investigation. This energy regime opens new opportunities for the discovery of new heavy particles (new gauge bosons), as well as new precise measurements in the Higgs sector (self-coupling, rare decays). However, high mass gauge bosons or high \(\hbox {p}_{\mathrm{T}}\) vector bosons decaying to pairs of hadrons require an efficient reconstruction of very high \(\hbox {p}_{\mathrm{T}}\) jets. The reconstruction of these boosted jets (\(\thicksim \)5–20 TeV), with a large fraction of highly energetic hadrons, sets the requirements on the calorimetry: excellent energy resolution (especially low constant term), containment of highly energetic hadron showers, and high transversal granularity to provide sufficient distinction of close by objects. Additionally the FCC detectors have to meet the challenge of a very high pile-up environment.

We will present the preliminary results of the ongoing performance studies, discuss the feasibility and potential of the technologies under test, while addressing the needs of the physics benchmarks of the FCC-hh experiment for the calorimeters.
