1. Phenomenological exploration of flavored Grand Unification through high-scale matching and renormalization group flow
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : The phenomenological success of the Standard Model (SM), and its unification of the electromagnetic and weak forces has inspired the search for a Grand Unified Theory (GUT), that dynamically reduces to the SM at low energies. In this work, we consider one such GUT, based on the trinification model [SU(3)]³ with an additional local SU(2) family symmetry, that is then broken directly to the gauge symmetry group of the SM.

2. 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 omorganisationAbstract : 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. Phenomenology of a Three Higgs Doublet Model with a U(1)xZ2 flavour symmetry
University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : We have studied the main features and the phenomenological consistency of a family-nonuniversal Three Higgs Doublet Model (3HDM) with a softly broken U(1)xZ2 family symmetry that enforces the flavour hierarchies in the Standard Model (SM) while implementing a tree-level Flavour Changing Neutral Current (FCNC) suppression in a Branco-Grimus-Lavoura way. Furthermore, the alignment limit is imposed in the scalar sector to enforce the physical scalar spectrum to accommodate a SM-like Higgs boson. READ MORE
