Description
The European Strategy for Particle Physics identified an electron-positron Higgs factory as the highest priority next flagship project. Precision measurements at these accelerators require calorimeters with excellent hadronic energy resolution ($\sim \frac{30\%}{\sqrt{E}}$) to successfully separate Z, W, and Higgs decays.
The dual-readout technique, which simultaneously measures scintillating and Cherenkov signals, improves energy resolution by compensating the effect of electromagnetic fraction fluctuations in hadron showers.
The highly granular Dual-Readout demonstrator (HiDRa), developed by different INFN units and Universities, combines dual-readout technique and high granularity information. It is based on capillary stainless steel tubes, with layers alternatively filled with two types of fibres, one detecting scintillation light and the other Cherenkov light. Its size allows the containment of hadronic showers.
In parallel, detailed GEANT4 simulations of the detector have been developed to model its expected behaviour and performance under various conditions.
The prototype underwent different testbeam campaigns. A dedicated data-analysis effort is ongoing to evaluate the detector performance and compare it with the requirements of future accelerators.
In this contribution, results from test-beam data and simulations are presented and compared in order to validate the accuracy of the models and assess their capability to reproduce the measured detector performance.
