1. 1. Phenomenological exploration of flavored Grand Unification through high-scale matching and renormalization group flow

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Hector Tiblom; [2023]
   Nyckelord :Grand Unification; GUT; trinification; spontaneous symmetry breaking; effective field theory; EFT; high-scale matching; renormalization group flow; Physics and Astronomy;

   Sammanfattning : 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.

3. 2. An Investigation of the Trinification Scalar Sector at One Loop

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Laurie Walk; [2017]
   Nyckelord :GUT; Trinification; Spontaneous Symmetry Breaking; Effective Field Theory; Effective Potential; Physics and Astronomy;

   Sammanfattning : 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.

4. 3. Unification in Particle Physics

   Kandidat-uppsats, Uppsala universitet/Högenergifysik

   Författare :Henrik Jansson; [2016]
   Nyckelord :particle physics; Grand Unified Theories; discrete family symmetry;

   Sammanfattning : 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. LÄS MER

5. 4. Left-right-symmetric model building

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Eric Corrigan; [2015]
   Nyckelord :Theoretical physics; particle physics; high-energy physics; left-right symmetry; grand unification; GUT; beyond standard model physics; BSM physics; Physics and Astronomy;

   Sammanfattning : 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. LÄS MER
