  1. 1. Exploring electroweak symmetry breaking in the scale-invariant Two-Higgs-Doublet Model

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Erik Rustas; [2023]
    Keywords : Two-Higgs-Doublet Models; 2HDM; Scale-invariance; Baryogenesis; BSM; Baryon Asymmetry; Coleman-Weinberg Potential; Theoretical Particle Physics; Physics and Astronomy;

    Abstract : This thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry.

  2. 2. Exploring a Two Higgs Doublet Model with a U(1) Family Symmetry and a Complex Singlet

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Michal Nowak; [2021]
    Keywords : Two Higgs Doublet Model; Complex Singlet Extension; Phenomenology; Physics Beyond the Standard Model; Branco-Grimus-Lavoura Model; Physics and Astronomy;

    Abstract : In this project a two Higgs doublet model with a complex singlet and an extra family symmetry providing a mechanism for suppression of flavor changing neutral currents is explored. The goal is to investigate the phenomenological consistency of the model using a custom software framework. READ MORE

  3. 3. Primordial Gravitational Waves and ultra-light Dark Matter in a complex singlet extended Standard Model

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Sara Wildenor; [2021]
    Keywords : theoretical physics; gravitational waves; dark matter; complex singlet extended standard model; LISA; BBO; DECIGO; Physics and Astronomy;

    Abstract : In this thesis, the consequences of extending the internal symmetries of the standard model with a complex singlet scalar field, are investigated in terms of dark matter phenomenology and the possibility of primordial gravitational wave detection utilizing space based laser interferometry. The scalar potential of the model is constructed with a Z2 symmetry, which allows for the retainment of a linear and a quadratic coupling parameter, as well as a stable dark matter candidate, and an additional non-zero vacuum expectation value for the real component of the scalar field.

  4. 4. Deep learning for non-intrusive sensing in turbulence with passive scalars

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Arivazhagan Geetha Balasubramanian; [2021]
    Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

    Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

  5. 5. Balancing between environmental impact and vibroacoustic performance for lightweight buildings

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Philip Carlsson; [2021]
    Keywords : Technology and Engineering;

    Abstract : Multi-storey buildings constructed in timber have become more common in recent years. A reason for this lies in the growing interest for sustainable building, where timber is seen as a particularly interesting alternative. READ MORE
