  1. 198. Recent dark-sector results from Belle II
    Steven Robertson (IPP / University of Alberta)

    Dark matter searches at accelerators
    Talk

    The Belle II experiment at the SuperKEKB collider has unique sensitivity to a broad class of models that postulate the existence of dark matter particles with MeV—GeV masses. This talk presents recent world-leading physics results from Belle II searches for long-lived scalar particles and Z’ decays; as well as the near-term prospects for other dark-sector searches.

  2. 225. Recent Results of Dark Sector Searches with the BaBar Experiment

    Dark matter searches at accelerators
    Talk

    Many scenarios of physics beyond the Standard Model predict new
    particles with masses well below the electroweak scale. Low-energy, high
    luminosity colliders such as BABAR are ideally suited to discover these
    particles. We present several recent searches for low-mass dark sector
    particles at BABAR, self-interacting dark matter, axion like particles
    and dark sector particles produced in B...

  3. 275. New Results from the Heavy Photon Search Experiment

    Dark matter searches at accelerators
    Talk

    The Heavy Photon Search experiment (HPS) at the Thomas Jefferson National Accelerator Facility searches for electro-produced dark photons.
    We present results from the 2016 Engineering Run consisting of 10608/nb of data for both the prompt and displaced vertex searches.
    A search for a resonance in the e+e− invariant mass distribution showed no evidence of signal, in
    agreement with...

  4. 311. First search for inelastic dark matter at the LHC with the CMS detector

    Dark matter searches at accelerators
    Talk

    Searches for dark matter at the LHC have largely focused on WIMPs, but what if instead of just one dark matter species, there exists a richer dark sector hidden from ordinary view? This opens up a whole new paradigm for dark matter searches, allowing us to focus not only on the coupling between dark matter and the standard model, but also on the interactions between dark matter constituents...

  5. 184. First results of the PADME Experiment and near-term plans

    Dark matter searches at accelerators
    Talk

    PADME is a fixed-target missing-mass experiment that searches for the dark photon and other dark sector particles using a beam of positrons with maximum energy of 500 MeV. The detector, located at the Laboratori Nazionali di Frascati near Rome, Italy, has already collected initial physics-grade data over the last few years. Here we present the first physics results of PADME, including one of...

  6. 318. The FASER experiment

    Dark matter searches at accelerators
    Talk

    FASER, the ForwArd Search ExpeRiment, is an LHC experiment located 480 m downstream of the ATLAS interaction point, along the beam collision axis. FASER and its sub-detector FASERnu have two physics goals: (1) to detect and study TeV-energy neutrinos, the most energetic neutrinos ever detected from a human-made source, and (2) to search for new light and very weakly-interacting particles....
