High-intensity muon beams could enable a muonium-based search for axions through resonant quantum transitions between hyperfine states. Combining theoretical calculations with simulation results, we demonstrate that such a muonium-based experimental approach could complement and tighten constraints on the axion-muon coupling beyond existing limits from the muon g−2 measurement, over the axion...
We propose here a set of new proposals and some preliminary experimental results involving probing and knocking with muons (PKMu). There is a wealth of rich physics to explore with GeV muon beams either from dedicated beam or cosmic source. Examples include but not limited to: muon scattering can occur at large angles, providing evidence of potential muon-philic dark matter or dark mediator...
Muon station for sciEnce technoLOgy and inDustrY (MELODY) is the first muon source project in China. It aims at both fundamental muon physics and muon applications in various fields. In phase I we will construct a surface muon beam with one muSR spectrometer and one test beam port for technology development and possible muon physics experiment. We also reserve the tunnel for a decay muon...
We propose DREAMuS (Dark matter REsearch with Advanced Muon Source), a fixed-target experiment at the High-Intensity Heavy-Ion Accelerator Facility (HIAF) in China, designed to search for muon-philic dark-sector particles. DREAMuS uses a GeV-scale muon beam to probe light mediators that preferentially couple to muons and induce lepton-flavor-violating muon-nucleus interactions, followed by...
