  1. 6. 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.

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

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

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

    Abstract : 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. READ MORE

  4. 8. General Relativity and Dynamical Universes

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Kajsa Fransson; [2021]
    Keywords : cosmology; general relativity; scale factor; friedmann equation;

    Abstract : The aim of this report is to explore different models of cosmology, depending on components as matter, radiation and dark energy. To be able to investigate the behaviour and age of these model universes, it is necessary to solve the Friedmann equation. READ MORE

  5. 9. Can Feebly Interacting Massive Particles (FIMP) constitute Dark Matter?

    University essay from KTH/Fysik

    Author : Grandharva Appagere; [2021]
    Keywords : Dark Matter; Higgs¬portal; Freeze¬-in mechanism; FIMP; C-W Mechanism; Mörk materia; Higgsportal; frys-in-mekanism; FIMP; C-W mekanism;

    Abstract : In this study, we investigate the feasibility of Feebly Interacting Massive particles (FIMP) as possible candidates to constitute the observed Dark Matter abundance in the universe. FIMPs are particles that couple very feebly with known particles in the Standard Model (SM). READ MORE

  6. 10. A literature review of FASERν - An emulsion detector for collider neutrinos

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

    Author : Lisa Andersson Loman; [2021]
    Keywords : physics; neutrinos; FASER; Standard Model; Beyond Standard Model; BSM; particles; elementary particles; neutrino cross sections; LHC; FASER nu; particle physics; physics experiment; CERN; long lived particles; Physics and Astronomy;

    Abstract : In 2021, the ForwArd Search ExpeRiment (FASER) will start searching for light and weakly coupled particles 480m from the proton-proton collision point of ATLAS at the Large Hadron Collider (LHC). The FASER main detector will have a sub-detector, FASERν, sensitive to high-energy collider neutrinos of all flavours. READ MORE
