Description
This work will present the full simulation and clustering algorithm development of a segmented crystal ECAL option for the IDEA detector, building upon previous 'proto-PFA' work previously simulated in Geant4 by M. Lucchini. On the simulation side, work has been done to integrate with the IDEA dual-readout and tracker packages, all within the latest key4hep framework, moving towards a unified detector description and simulation toolkit. Preliminary work on new clustering algorithms leveraging the full granularity and longitudinal segmentation of the crystals and timing layer will be presented. The physics case for the IDEA+crystals option in the context of probing the Higgs tri-linear self-coupling will also be discussed with a focus on detector-specific characteristics that we advocate as the basis for performance benchmarks for the FCC-ee.
