A new hadronic calorimeter (HCAL) with glass scintillator tiles has been designed for future lepton collider experiments (e.g. the Circular Electron Positron Collider). Using a sampling structure (similar to CALICE AHCAL technology), HCAL design aims better hadron and jet performance, higher fraction by using high-density instead of plastic scintillator. Full simulation studies were done on performance Higgs decays Particle-Flow Algorithm (PFA). The was optimised in terms longitudinal depth,...
To achieve the physics goal of precisely measuring Higgs, Z, W bosons and top quark, future electron-positron colliders, such as Circular Electron Positron Collider (CEPC), require that their detector systems have unprecedented high jet energy resolution.

Abstract Precision measurements of properties the Higgs, W and Z bosons are key scientific goals at future e + - Higgs factories. A main challenge for these is to fulfill an unprecedented jet energy resolution, design hadronic calorimeter (HCAL) found be one most important factors.

Based on the particle-flow paradigm, a new hadronic calorimeter (HCAL) with scintillating glass tiles is proposed to address major challenges from precision measurements of jets at future lepton colliders, such as Circular Electron Positron Collider (CEPC). Tiles high-density glass, high-energy sampling fraction, can significantly improve energy resolution in low-energy region (typically below 10 GeV for jet components Higgs factories). The single hadrons and effects key parameters have been...

A pico-second timing (PIST) front-end electronic chip has been developed using $55~\mathrm{nm}$ CMOS technology for future electron-positron collider experiments (namely Higgs factories). Extensive tests have performed to evaluate the performance of a dedicated SiPM-readout system equipped with PIST chip. The results show that resolution can achieve $45~\mathrm{ps}$ SiPM signals at minimum-ionizing particles (MIP) level ($200~\mathrm{p.e.}$) and better than $ 10~\mathrm{ps}$ larger...
