  1. 16. Using Neural Networks to Probe the Parameter Space of a 3HDM with a U(1) times Z2 Flavor Symmetry

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Ludvig Siwe; [2020]
    Keywords : Three Higgs Doublet Model; 3HDM; Machine Learning; Neural Network; Genetic Algorithm; Physics and Astronomy;

    Abstract : Probing the physical regions in large parameter spaces of typical Standard Model (SM) extensions can be a very difficult computational task. In this thesis project, a new framework has been developed that utilises well-known Machine Learning (ML) techniques in the form of neural networks trained by a genetic algorithm. READ MORE

  3. 17. Dark Matter – Direct Detection and Capture in the Sun

    University essay from KTH/Fysik

    Author : Erika Lind; [2020]
    Keywords : Dark matter; direct detection; indirect detection; solar capture; inelastic dark matter; Mörk materia; direkt detektion; indirekt detektion; solinfångning; inelastisk mörk materia;

    Abstract : Dark matter has been inferred from various observations such as in galaxy clusters, flat galactic rotation curves, gravitational lensing measurements and the cosmic microwave background. Despite overwhelming observational evidence and ongoing searches, a clear signal of dark matter has not yet been detected. READ MORE

  4. 18. The spatial distribution of dark matter in the Universe

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Tamina Lund; [2020]
    Keywords : dark matter halos; NFW profile; curve fitting; Bayesian inference; least Squares; data uncertainties; Physics and Astronomy;

    Abstract : It was previously found that the density profile of dark matter halos is well-fit by a universal, smooth function over a vast range of masses and redshifts, named the Navarro-Frenk-White (NFW) profile after its discoverers. Despite its impressive goodness of fit, the NFW model remains an approximation of the density profile of realistic halos. READ MORE

  5. 19. Synergies between Gaia, LSST and LISA

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Isabella Danaliv; [2020]
    Keywords : Gaia; LSST; LISA; telescope; synergies; multi-messenger; Physics and Astronomy;

    Abstract : The scientific development of astronomy today mainly comes from the information that can be obtained via electromagnetic radiation. Today, the Gaia optical telescope is one of the most ambitious space projects man has ever completed. Another optical telescope LSST is designed to complement Gaia. READ MORE

  6. 20. Extending the Standard Model by a Dark and Visible Scalar Singlet

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Aram Fatah; [2020]
    Keywords : The two real singlet model; higgs boson; dark matter; beyond the standard model; bsm; scalar; Physics and Astronomy;

    Abstract : In this thesis, we extend the Higgs sector of the Standard Model by two scalar singlets and impose a discrete Z2 symmetry on each of them, under which, both singlets are odd. One of the two scalar singlets will acquire a vacuum expectation value while the other one does not. READ MORE
