  3. 4. Observability of the Higgs boson decay to a photon and a dark photon (remote)
    Hugues Beauchesne (NCTS)

    Many collider searches have attempted to detect the Higgs boson decaying to a photon and an invisible massless dark photon. For the branching ratio to this channel to be realistically observable at the LHC, there must exist new mediators that interact with both the standard model and the dark photon. In this talk, we present experimental and theoretical constraints on an extensive set of...

    Jinmian Li (Sichuan University)

    The dark shower is a common phenomenon for particles in the dark sector which take part in strong interactions and are boosted. We first discuss the detection prospect of accelerated DM through cosmic ray upscattering at the XENON1T and Super-K experiments. We emphasize that the radiated dark photon from the boosted DM can possibly be probed at the DUNE and JUNO experiments. In the second...

  10. 31. Detecting Dark Photons with Superconducting Radio-Frequency (SRF) Cavities
    Yanjie Zeng
    20/10/2023, 17:55

    Dark photons are well-motivated hypothetical gauge particles of a hidden U(1) symmetry, which is an extension of the standard model. As ultralight bosons, dark photons can either constitute wavelike dark matter candidates, or form a relativistic background through the decay from dark matter. Through the kinetic mixing with electromagnetic photons, dark photons can induce an effective current...
