Description
Dual-readout calorimetry is a promising approach to achieve improved hadronic energy resolution by simultaneously measuring scintillation and Cherenkov signals using dedicated fiber readout. This technique enables event-by-event correction of fluctuations in the electromagnetic shower fraction, and is considered a strong candidate for calorimetry at future collider experiments such as CEPC and FCC. The Korea dual-readout calorimeter (DRC) collaboration has been developing a copper-based dual-readout calorimeter over the past several years, including high-granularity readout structures. In this contribution, we present a comprehensive overview of the activities of the Korea DRC collaboration. This includes the design and development of the detector prototypes, as well as the results obtained from the 2025 CERN SPS test beam campaign. The detector performance is evaluated for both electromagnetic and hadronic showers. In addition, future plans, including the upcoming test beam in 2026 and long-term prospects, are discussed.
