  • Descrição: The physics reach and feasibility of the Future Circular Collider (FCC) with centre of mass energies up to 100 TeV and unprecedented luminosity has delivered a Conceptual Design Report early 2019. 100 TeV proton-proton collisions will produce very high energetic particle showers in the calorimeters from both, jets and composite objects such as boosted bosons/tops. The reconstruction of such objects sets the calorimeter performance requirements in terms of shower containment, energy resolution and granularity. Furthermore, high-precision measurements of photons and electrons over a wide energy range are crucial to fully exploit the FCC-hh physics potential, especially given the large amount of collisions per bunch crossing the detectors will have to face (pile-up of 0⟨μ⟩=100). The current reference technologies for the calorimeter system of the FCC-hh detector are presented: Liquid Argon (LAr) as the active material in the electromagnetic calorimeters, and the hadronic calorimeters for |η|>1.3 (Endcap and Forward region), and a Scintillator-Steel (Tile) calorimeter as hadronic calorimeter in the Barrel region. The paper will focus on the performance studies for single particles and jets in the combined calorimeter system. We will introduce the simulation framework and the reconstruction chain, that includes the calibration and clustering of calorimeter cells and the estimation of the electronics as well as the pile-up induced noise. In conclusion, the achieved performances will be compared to the physics benchmarks of the FCC-hh experiment.
