Abstract
The muon trident process, which involves coherent scattering to produce tau pairs, is a powerful tool for constraining dark sectors. We propose to explore this channel using future high-energy muon beams with the dedicated active-target detector, High-Energy Muon Electronic Research Apparatus (HEMERA). The detector would complement muon beam-dump searches by resolving prompt signatures and could operate from preparatory facilities involving an individual muon beam to the full Muon Collider. We illustrate its capabilities for a leptophilic scalar with Yukawa-like couplings that can mediate thermal dark matter production. With10¹⁸incident TeV-scale muons, even a compact 10 kg silicon-based HEMERA will extend currentB -factory and(g-2)_(μ)bounds by over an order of magnitude in coupling strength, providing an additional compelling motivation for the development of high-energy muon beam infrastructure.
