Abstract
The future proton-proton collider (FCC-hh) will deliver collisions at a center of mass energies up to √s = 100 TeV at an unprecedented instantaneous luminosity of L = 3 1035cm−2s−1, resulting in extremely challenging radiation conditions up to a maximum of 5 1018cm2MeV neutron equivalent fluence and dose up to 5 GGy in the forward calorimeters (up to |η| = 6) and up to 1000 simultaneous proton-proton interactions per bunch-crossing. By delivering an integrated luminosity of few tens of ab−1, the FCC-hh will provide an unrivalled discovery potential for new physics. Requiring high sensitivity for resonant searches at masses up to tens of TeV imposes strong constraints on the design of the calorimeters. Resonant searches in final states containing jets, taus and electrons require both excellent energy resolution at multi-TeV energies as well as outstanding ability to resolve highly collimated decay products resulting from extreme boosts. In addition, the FCC-hh provides the unique opportunity to precisely measure the Higgs self-coupling in the di-photon and b-jets channel. Excellent photon and jet energy resolution at low energies as well as excellent angular resolution for pion background rejection are required in this challenging environment.

Summary
The Future Circular Collider (FCC) is the ambitious project of an accelerator complex in the CERN area for the after LHC era. The main drive on the complex tunnel and infrastructure is set by a 100 TeV hadron circular collider (FCC-hh). Such center of mass energy can be achieved by means of a 100 km tunnel and 16 T bending dipole magnets. The FCC-hh will deliver a peak luminosity of L = 3 1035 cm−2s−1 in its ultimate phase. This will result in O(20) ab−1 of integrated luminosity per experiment.
