  1. 1. Pulse Amplitude Reconstruction in the LDMX Hadronic Calorimeter Readout

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Aksel Draguanov Mihaylov; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The universe shows signs of containing some invisible matter, known as dark matter. There are many possible constituents for dark matter, one such being light dark matter which would interact with ordinary matter through a new mediator force and have masses in the range of a few MeV to GeV.

  3. 2. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Jacob Lindahl; [2023]
    Nyckelord :LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

    Sammanfattning : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. LÄS MER

  4. 3. Simulation of a prototype of the LDMX hadronic calorimeter and analysis of test beam data

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Péter György; [2022]
    Nyckelord :LDMX; HCal; TS; prototype; Physics and Astronomy;

    Sammanfattning : The Light Dark Matter eXperiment (LDMX) is an upcoming experiment to test the existence of dark matter in the mass range of 1 MeV - 1 GeV. It does so by looking for missing momentum and energy in collisions of an electron beam and a tungsten target, which could potentially indicate the existence of dark matter. LÄS MER

  5. 4. Rejection of the Photon Induced Background in LDMX at 8 GeV

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Erik Wallin; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The Light Dark Matter eXperiment (LDMX) is a proposed fixed target experiment at SLAC's LCLS-II electron beamline that will attempt direct production of sub-GeV dark matter, measurable through a missing momentum and missing energy signature. An initial run of LDMX is planned at 4 GeV beam energy, for which a study on LDMX's capabilities to separate dark matter production events from the standard model background was previously performed.

  7. 5. Investigating the Electron Reconstruction Efficiency at the LHCb

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Martin Andersson; [2021]
    Nyckelord :;

    Sammanfattning : An exploratory investigation of the electron reconstruction efficiencyat the LHCb is presented. The study is done through simulations ofparticle interaction with the full LHCb detector setup, both by firingsingle particles into the detector and by generating the decay of Bmesons into J/psi K, where the J/psi decays into dileptons.
