  1. 1. Validation of simulation with enhanced kaon production to investigate kaon background for LDMX

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

    Författare :Lisa Andersson Loman; [2023]
    Nyckelord :Dark matter; experimental physics; simulations; kaons; particle physics; LDMX; background studies; mörk materia; partikelfysik; kaoner; Physics and Astronomy;

    Sammanfattning : Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. LÄS MER

  3. 2. 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.

  4. 3. Dwarf Galaxies in the Galactic Potential as probes of its internal structure

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Arn Marklund; [2022]
    Nyckelord :Numerical integration; Stellar Streams; Dwarf Galaxies; Dark Matter; Physics and Astronomy;

    Sammanfattning : Satellite galaxies on bound orbits around the Milky Way (MW) are constantly subject to tidal forces from the MW. If the tidal forces are large enough, they may strip the outermost stars of the satellite, that in turn distribute themselves in long elongated stellar streams. LÄS MER

  5. 4. Observing stellar streams made in a supercomputer

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Erik Fridén; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Stellar streams are made of stars that originate from globular clusters or dwarf satellite galaxies that have been disturbed by the gravitational pull from the galaxy they orbit. These stellar streams hold information about the history of the progenitor as well as information about the gravitational potential of the host galaxy. LÄS MER

  7. 5. Dark Matter Subhalos Gravitational Dynamics and Evolution

    Kandidat-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Edvin Zigmanovic; [2014]
    Nyckelord :dark matter; subhalos; Physics and Astronomy;

    Sammanfattning : In this thesis, I present a case where Dark Matter subhalos would annihilate at some stage in their lifetime. The implication of this scenario could potentially aid the Missing Satellites and the Cusp-Core density profile problem. LÄS MER
