Hadron calorimetry at the FCC-hh experiment

The new energy regime of the Future Circular Collider (FCC) in hadron mode with centre of mass energies up to 100\,TeV opens the opportunity for the discovery of physics beyond the standard model. At 100 TeV a large fraction of the W,Z, H bosons and top quarks are produced with a significant boost. It implies an efficient reconstruction of very high energetic objects decaying hadronically and producing high $p_{T}$ jets in the detector. The reconstruction of those boosted objects is challenging and sets the calorimeter performance requirements in terms of energy resolution, containment of highly energetic hadron showers, and high transversal granularity. \
We will present the current baseline technologies for the calorimeter system for the barrel region of the FCC-hh baseline detector: a Liquid Argon (LAr) electromagnetic and a Scintillator-Steel (Tile) hadron calorimeter. The talk will focus on the performance studies for hadrons, in terms of single particle and jet reconstruction. We will present the achieved energy resolutions and dependences on the sampling fraction and granularity. Additionally, design considerations will be discussed and we will introduce future plans that includes the application of particle flow algorithms.
