  4. 83. Search for Dark Matter in events with missing transverse momentum and a Higgs boson decaying into b-quarks with the ATLAS detector
    Eleni Skorda (Lund University (SE))

    Regular talk

    In hadron colliders, the proton constituents that participate in the hard scatter have almost no momentum in the transverse plane. Any imbalance observed in this plane for the products of the scatter can be interpreted as particles escaping detection. Such events can originate from Standard Model processes involving neutrinos, but might also have a more “exotic” origin. One possible...

  5. 76. Status and Prospects of Light Dark Matter eXperiment
    Ruth Pottgen (Lund University (SE))
    22/11/2021, 11:00
    Regular talk

    An elegant explanation for the origin and observed abundance of dark matter in the Universe is the thermal freeze-out mechanism. Within this mechanism, possible masses for dark matter particle candidates are restricted approximately to the MeV - TeV range. The GeV-TeV mass range is being explored intensely by a variety of experiments searching for Weakly Interacting Massive Particles. The...

  6. 87. Light Dark Matter eXperiment Rejection of Photon Induced Background at 8 GeV
    Erik Wallin (Lund University (SE))
    22/11/2021, 11:15
    Regular talk

    Viewing dark matter as thermal relics from the early universe necessitates possible dark matter production in accelerator experiments. The dark matter mass range below one GeV, in the "hidden sector", is so far less explored. The Light Dark Matter eXperiment (LDMX) is a proposed fixed target experiment that aims to be sensitive to dark matter around and below the proton mass, where few-GeV...

  7. 86. simulation and testing of the Light Dark Matter eXperiment prototype trigger and hadronic calorimeter
    Peter Gyorgy (Lund University (SE))
    22/11/2021, 11:30
    Regular talk

    Dark matter is a theorized, yet unknown form of matter that makes up the majority of the mass of the Universe. One compelling explanation for its origin is the thermal freeze-out mechanism, which posits its mass to be somewhere in the MeV to TeV range. While dark matter with mass above 1 GeV is being thoroughly searched for by an ample amount of experiments, very few experiments to date search...

  8. 84. Progress towards a program of searches for neutron conversions at the European Spallation Source with the HIBEAM/NNBAR experiment
    Bernhard Meirose (Stockholms Universitet)
    22/11/2021, 11:45
    Regular talk

    Baryon number violation (BNV) is needed to explain the origin of the matter-antimatter asymmetry and routinely appears in theories which extend the Standard Model of particle physics. However, BNV is yet to be observed. The HIBEAM/NNBAR program is a two stage set of experiments (HIBEAM then NNBAR) to search for neutron conversions to sterile neutrons and anti-neutrons at the European...

  9. 82. Updates on the HIBEAM/NNBAR Prototype Calorimeter at Stockholm
    Katherine Dunne (Stockholm University (SE))
    22/11/2021, 12:00
    Regular talk

    The HIBEAM/NNBAR experimental program will be the cutting-edge free neutron search for n→nbar and n→sterile n oscillations, with an ultimate sensitivity gain of more than three orders of magnitude compared to what was previously achieved. A key component of the program is the annihilation detector which will identify a neutron-antineutron annihilation event within a carbon foil target through...
