SUMMARY:Challenges and detector concepts for future collider calorimetry
DESCRIPTION:Speaker: Ruben Gargiulo (La Sapienza Univ.\, Roma) \nFuture colliders\, including proposed Higgs factories\, pose demanding requirements on calorimetry. In particular\, precision measurements of Higgs boson properties and multi-jet final states require significant improvements in jet energy resolution. These requirements can be addressed through fine transverse granularity\, longitudinal segmentation\, and optical dual-readout. Such features allow efficient particle-flow jet reconstruction\, photon and neutral pion separation\, and reduced fluctuations in the reconstructed energy of hadronic showers due to invisible energy lost in nuclear breakup and reactions. This talk reviews the physics motivations behind the stringent jet energy resolution requirements of Higgs factories and discusses detector concepts currently being explored\, including ongoing activities within the DRD6 collaboration. Particular emphasis is placed on how jet energy resolution requirements influence the design of the electromagnetic section of calorimeters while maintaining excellent electromagnetic energy resolution and timing performance. A significant example is the R&D on the CRILIN electromagnetic calorimeter\, based on small Cherenkov crystals with longitudinal segmentation and a timing resolution of about 20 ps\, developed at LNF for the muon collider but suitable for several future colliders \n
