Description
Particle flow algorithm (PFA) and dual-readout are advanced calorimeter technologies proposed for precise jet energy measurements at future colliders. PFA requires highly granular calorimeters for efficient particle separation and optimal energy reconstruction depending on particle type. Dual-readout improves hadronic energy resolution by incorporating both scintillation and Cherenkov detectors, enabling event-by-event identification of the electromagnetic fraction within hadronic showers. Integrating these two technologies into a single calorimeter system poses significant challenges, as conventional dual-readout systems often rely on optical fibers, which are incompatible with the fine segmentation required by PFA. This study explores a novel approach to realize such a hybrid calorimeter by introducing tile-segmented Cherenkov layers into a calorimeter system used at Higgs factory. The expected improvement in energy resolution, achieved by combining these technologies, is evaluated through detailed simulation studies and will be presented in this conference.
