“…However, a further increase of the η granularity of the HB is not improving the jet angular resolution significantly which supports the choice for the reference detector design. Studies of the cell granularity of the hadronic calorimeter, optimised for jet substructure variable, have shown similar results [53] and support the chosen granularity of ∆η × ∆φ = 0.025 × 0.025 for the hadronic calorimeter. Including more sophisticated jet reconstruction techniques like particle flow algorithms or DNNs could be however more sensitive to the granularity and thus point into another direction.…”

The future proton-proton collider (FCC-hh) will deliver collisions at a center of mass energy up to √ s = 100 TeV at an unprecedented instantaneous luminosity of L = 3 10 35 cm −2 s −1 , resulting in extremely challenging radiation and luminosity conditions. 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. This report describes the calorimeter studies for a multi-purpose detector at the FCChh. The calorimeter active components consist of Liquid Argon (LAr), scintillating plastic tiles (Tile) and Monolithic Active Pixel Sensors (MAPS) technologies. The technological choices, design considerations and achieved performances in full Geant4 simulations are discussed and presented.

“…Thanks to the superior tracker segmentation, we find Track-jets to perform better in terms of QCD background rejection despite the slightly worse jet mass resolution. A recent study shows that the reconstruction of jet substructure variables for highly boosted objects will benefit from small cell sizes of the hadronic calorimeter which confirms the FCC baseline design [57].…”

Heavy resonances at energy-frontier hadron colliders

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 that could be discovered by the end of High-Luminosity LHC (HL-LHC).

“…There are several detector technologies that will improve JSS and related techniques. These include finer calorimeter granularity [127,128], more hermetic coverage of tracking detectors, and precise measurements of timing information. The experience of the LHC has shown that such information can be used to more accurately reconstruct the interaction of hadrons with various detector elements, much of which is used in the "particle flow" (PF) [129] concept already deployed by the LHC experiments.…”

Jets and Jet Substructure at Future Colliders

Even though jet substructure was not an original design consideration for the Large Hadron Collider (LHC) experiments, it has emerged as an essential tool for the current physics program. We examine the role of jet substructure on the motivation for and design of future energy Frontier colliders. In particular, we discuss the need for a vibrant theory and experimental research and development program to extend jet substructure physics into the new regimes probed by future colliders. Jet substructure has organically evolved with a close connection between theorists and experimentalists and has catalyzed exciting innovations in both communities. We expect such developments will play an important role in the future energy Frontier physics program.
