  1. 3. Probing axion-like particles with multimessenger observations of neutron star mergers

    Axion-like particles (ALPs) can be copiously produced in binary neutron star (BNS) mergers through nucleon-nucleon bremsstrahlung if the ALP-nucleon couplings $g_{a N}$ are sizable. Furthermore, the ALP-photon coupling $g_{a\gamma}$ may trigger conversions of ultralight ALPs into photons in the magnetic fields of the merger remnant and of the Milky Way. This effect would lead to a potentially...

    The Any Light Particle Search II (ALPS II), a light-shining-through-a-wall experiment located in Hamburg, Germany at the Deutsches Elektronen-Synchrotron (DESY), completed its first science runs in early 2024. The experiment principally searched for axions and axion-like particles in two data-taking stretches deemed a "scalar" run and a "pseudoscalar" run. The analysis of the data from these...

    The QCD axion is a compelling dark matter candidate for its natural emergence as a solution to the strong CP problem. Recent advancements in dilution refrigeration and quantum amplification technologies have enabled the Axion Dark Matter eXperiment (ADMX) to probe the well-motivated axion mass range for both benchmark models: Kim–Shifman–Vainshtein–Zakharov (KSVZ) and...

    Cavity haloscopes remain the most sensitive approach for searching for

    axion dark matter, utilizing resonant microwave cavities in strong
    magnetic fields to detect axion-induced photons.

    The Center for Axion and Precision Physics Research (CAPP) has
    established a world-class experimental facility to advance this
    technique in Korea.

    Building on this foundation, the Dark...
