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

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Aksel Draguanov Mihaylov; [2023]
    Keywords : Physics and Astronomy;

    Abstract : 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

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

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

    Abstract : 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. READ MORE

  4. 3. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment

    University essay from KTH/Fysik

    Author : Simon Thor; [2022]
    Keywords : ATLAS; CERN; particle physics; simulation; Python; C ; standard model; emerging jets; long-lived particles;

    Abstract : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. READ MORE

  5. 4. Complementarity of high energy and high intensity experiments for dark photon benchmarks

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Joshua Greaves; [2022]
    Keywords : Dark matter; LDMX; Dark photon; Complementarity; Snowmass; Relic density; Thermal relic; Relic abundance; Cross section; Constraints; Limits; Minimal models; Energy frontier; Intensity frontier; Madgraph; Madanalysis; Vector mediated; Physics and Astronomy;

    Abstract : Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others.

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

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Erik Wallin; [2022]
    Keywords : Physics and Astronomy;

    Abstract : 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.
