A hadronic calorimeter based on resistive micropattern gaseous detectors

Experiments at future Higgs factories will require excellent energy resolution to discriminate hadronic decays of W/Z and H bosons effectively. To meet this target, calorimeters must feature fine-granularity readouts, essential for implementing the Particle Flow Algorithm (PFA). In this context, an innovative hadronic calorimeter (HCAL) design has been explored, employing resistive Micro Pattern Gaseous Detectors (MPGDs) as active layers. These technologies provide excellent spatial and time resolution, high radiation hardness, and fine-granularity readout, making them ideal for future circular collider experiments optimized for the PFA. This contribution summarizes the results of performance studies conducted on an MPGD-based HCAL standalone Geant4 simulations and benchmarked within the full Muon Collider simulation framework. Results of characterization tests performed with muon beams at the SPS on resistive MPGDs, focusing on efficiency and response uniformity, are also presented. Additionally, the energy response of an HCAL cell prototype is discussed based on beam tests at the PS with pions up to 10 GeV.
