Description
The "Muon Puzzle" remains a discrepancy in cosmic-ray physics, where observed muon characteristics, including the number, lateral spread and energy distribution, differ significantly from the theoretical predictions of hadronic interaction models and primary mass composition.
To provide an observational benchmark for this discrepancy, This study employs the Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND) and Super-Kamiokande, which are two kiloton-scale underground detectors. A coincidence search between these two detectors probes the event rate of muon bundles spread over O(100) m, far exceeding the reach of single underground detectors.
As an initial step, this poster reports the expected coincidence muon rate, evaluated through simulations of air shower development and rock propagation.
