Description
For future e-e+ Higgs factories, such as the Circular Electron Positron Collider (CEPC), precision measurements of properties of the Higgs, W and Z bosons are the key scientific goals. A main challenge for these goals is to fulfill an unprecedented jet energy resolution, and the design of the hadronic calorimeter (HCAL) is found to be one of the most important factors. Then, a novel design of the particle flow oriented hadronic calorimeter based on glass scintillators (GSHCAL) was proposed recently. By using high-performance glass scintillators featuring high density, high light yield and short decay time, the GSHCAL can be beneficial for a better jet energy resolution and more compact structure in a cost-effective way. In this contribution, the optimizations for several key design parameters of the GSHCAL are discussed and the performances in different GSHCAL designs are compared, in order to balance the key physics performance and the cost, as well as the engineering complexity.
