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. An Investigation of the Trinification Scalar Sector at One Loop
University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : Throughout this work we investigate a trinification-based grand unification theory (GUT) with a global family symmetry, as a radiative origin of the Standard Model (SM). We show that after spontaneous symmetry breaking of the trinification gauge group, we can in theory construct an effective left-right symmetric model (LRSM) which breaks to the SM gauge group through radiative breaking induced by the running of the model’s parameters.

3. Unification in Particle Physics
University essay from Uppsala universitet/HögenergifysikAbstract : During the twentieth century, particle physics developed into a cornerstone of modern physics, culminating in the Standard Model. Even though this theory has proved to be of extraordinary power, it is still incomplete in several respects. READ MORE

4. Left-right-symmetric model building
University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationAbstract : We have studied left-right-symmetric (LR) model building in two specific instances: the Minimal Left-Right-Symmetric Model (MLRM), with gauge group SU(3)_C × SU(2)_L × SU(2)_R × U(1)_{B-L} and parity as the LR symmetry; and a non-supersymmetric, trinified theory, with gauge structure SU(3)_L × SU(3)_R × SU(3)_C × Z_3 and an additional, novel, SU(3) family symmetry. For the MLRM, we have rederived the Lagrangian in the gauge and mass eigenbases, partly using the SARAH model building framework. READ MORE

5. Grand Unified Theories: SU(5), SO(10) and supersymmetric SU(5)
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : A brief summary of the Standard Model of particle physics is presented with some of its problems listed. After this some necessary concepts and mathematics are introduced. READ MORE
