    Description

    Precision measurements of the Higgs boson and electroweak interactions at future $e^+e^-$ collider experiments, such as the ILC, CLIC, and FCC-ee, are crucial for exploring new physics. Achieving this requires a high-granularity electromagnetic calorimeter, for which the silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is one of leading candidates. While previous physics prototypes validated the fundamental concept, demonstrating the performance of a technological prototype designed under realistic mechanical and electronic constraints remains a key milestone. This study focuses on the analysis of beam test data collected in June 2026 at the CERN SPS, utilizing a 15-layer SiW-ECAL technological prototype developed for future Higgs factories. In this presentation, we present the results of calibration and energy reconstruction.
