  1. 1. Energy reconstruction with artificial neural networks on LDMX simulations

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Magdalinski; [2020]
    Keywords : Dark matter; LDMX; electromagnetic calorimeter; neural networks; convolutional neural networks; Physics and Astronomy;

    Abstract : It is clear from evidence such as rotational curves and cosmic microwave background measurements that dark matter exists. The light dark matter experiment (LDMX) will search for dark matter in the sub-GeV range. It will do this using missing-momentum measurements of electrons interacting with a Tungsten target.

  2. 2. Test setup for LDMX HCal readout

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Joshua Greaves; [2020]
    Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  3. 3. Signal and Background Studies at 8 GeV for the Light Dark Matter eXperiment

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Péter György; [2020]
    Keywords : LDMX; Dark Matter; Light Dark Matter; 8 GeV; Physics and Astronomy;

    Abstract : Light dark matter is a hypothesized form of dark matter in the 1 MeV to 1 GeV mass range. The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of light dark matter, by colliding an electron beam with a tungsten target and assembling a set of events that potentially indicate the existence of light dark matter.

  4. 4. Review of DM searches in the ATLAS and LDMX experiments

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Disa Gustafsson; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Several findings show that dark matter makes up 27% of the universe. The goals of this thesis are to understand some of the most important evidences and candidates for dark matter, as well as how dark matter is searched for. The ATLAS and LDMX experiments are reviewed to give a greater insight into the search for dark matter. READ MORE

  5. 5. Imaging Using Machine Learning for the LDMX Electromagnetic Calorimeter

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Leo Östman; [2020]
    Keywords : Physics and Astronomy;

    Abstract : LDMX is a fixed target experiment designed to search for light dark matter. The experiment will search for dark matter signatures using missing momentum and energy in events with electrons scattering in the target. READ MORE
