An example of the shower produced by a 10 GeV pion interacting in the 40L-PFQ tower
Abstract
Calorimeters with dual readout measure both scintillation and Cherenkov light produced in their active media. They offer improvements in energy resolution and, therefore, have become increasingly interesting due to the need for precision jet measurements at Higgs factories. This paper presents GEANT4 simulations of single-particle responses in sampling and homogeneous calorimeters, and demonstrates the effect of inclusion of Cherenkov light in the reconstruction of energies.

In this paper we report the results of the GEANT4 simulation of optical photons created as the results of collisions with single particles with the energy 1 – 40 GeV. For the first time, the simulations were performed for the traditional HCAL tower considered for the ILC, CLIC, CLD and similar experiments, but after adding additional active layers to collect Cherenkov signals.
