Abstract
The Multi-TeV Muon Collider is proposed as a promising tool for advancement in understanding the Standard Model within the European particle physics strategy. The Muon Collider physics program focuses on precise measure- ments in the Higgs boson sector and exploring new physics at the TeV scale. Achiev- ing these goals requires accurate full-event reconstruction, with the Particle Flow (PF) algorithm as a suitable approach. This algorithm utilizes information from tracking, calorimeter, and muon detectors for particle identification and momen- tum/energy measurements. The challenge lies in discriminating μμ collision prod- ucts from the intense beam-induced background (BIB) due to the unstable nature of muons. To address this, an innovative hadronic calorimeter (HCAL) based on Mi- cro Pattern Gas Detectors (MPGDs) is proposed. MPGDs offer robust technology for high radiation environments and high granularity for precise spatial measure- ments. Dedicated studies are needed to assess and optimize the performance of the MPGD-based HCAL, including developing prototypes as proof of concept. Monte Carlo simulations using Geant4 evaluate the HCAL’s response to incoming parti- cles, comparing digital and semi-digital readouts with energy resolution as the key metric. The simulated geometry is integrated into the Muon Collider software to analyze its impact on jet reconstruction amid the full apparatus and in the pres- ence of BIB. Validation involves testing a small-size calorimeter cell equipped with resistive MPGD technologies like MicroMegas, μRWELL, and RP-WELL.
