Abstract:

The European Strategy for Particle Physics has identified an e+e- Higgs factory as the highest priority next collider to address the fundamental physics questions which remain open. The international community has started to organize the R&D efforts to study the feasibility of such a collider, identify physics-driven detector requirements and the design of next generation particle detectors of which calorimeters represent a central system.

The long history of crystal homogeneous calorimeters in pushing the frontier of high energy resolution measurements for EM particles represent a unique opportunity compared to other sampling calorimeter technologies. Furthermore, recent technological developments in the fields of crystal manufacturing and photodetector developments (SiPMs) have opened new perspectives on how a segmented crystal calorimeter with dual-readout capabilities could be exploited for particle detectors at future collider experiments.

Based on the simultaneous measurement of scintillating and Cherenkov light, the dual-readout calorimetric technique is designed compensate the fluctuations of the electromagnetic shower fraction on an event-by-event basis, significantly improving hadronic shower energy measurements. Such technology shows impressive potential, in particular when coupled with a highly granular readout system. On top of that, time measurements may complement the 2D imaging capabilities of a fibre-sampling calorimeter and provide information on the shower longitudinal profile. 

The potential and expected performance of dual-readout calorieters will be discussed in the context of future e+e- Higgs Factories like FCC-ee or CEPC, as well as their integration in the calotimeters of proposed experiments, like the IDEA detector.
