1. 21. Inridningens påverkan på symmetrin i unghästars rörelsemönster

   University essay from SLU/Dept. of Clinical Sciences

   Author : Lisa Marie Andersson; [2017]
   Keywords : rörelsemönster; symmetri; rörelseasymmetrier; inridning; Lameness Locator;

   Abstract : Det idag viktigaste medicinska problemet hos svenska ridhästar är hälta. Detta orsakar hästarna lidande och många hästar avlivas varje år på grund av hälta. READ MORE

3. 22. A supersymmetric, E8 inspired, unification model

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Astrid Ordell; [2016]
   Keywords : Physics and Astronomy;

   Abstract : The thesis treats the construction of a supersymmetric model, inspired by an E8 unfication scenario. Via the introduction of adjoint representation chiral superfields, in combination with the inclusion of a global generation symmetry, the Standard Model fermion candidates are protected from gaining any mass until electroweak symmetry breaking.

4. 23. Strongly First Order Phase Transitions and The Possibility of Electroweak Baryogenesis in General Two-Higgs-Doublet Models

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nils Hermansson Truedsson; [2016]
   Keywords : Two-Higgs-Doublet Models; 2HDM; Electroweak Phase Transition; Baryon Asymmetry; Electroweak Baryogenesis; Beyond Standard Model; BSM; Theoretical Particle Physics; Physics and Astronomy;

   Abstract : The possibility to have a strongly first order electroweak phase transition, which is one of the Sakharov conditions for electroweak baryogenesis together with $\mathcal{CP}$ violation and baryon number violation, in general Two-Higgs-Doublet Models (2HDMs) is here investigated. Different kinds of $\mathbb{Z}_{2}$ breaking beyond standard assumptions are studied, in particular by allowing it to be completely broken as well as by assuming it to be only approximately preserved in the Yukawa sector.

5. 24. Renormalization in Field Theories

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Alexander Söderberg; [2015]
   Keywords : renormalization in field theories; renormalization; quantum field theories; quantum field theory; quantum mechanics; quantum physics; quantum; physics; mechanics; field theory; theory; theories; fields; field; regularization; dimensional regularization; dimensional; perturbative; perturbative renormalization; wilsonian approach; wilsonian; approach; momentum cutoff; momentum; cutoff; callan; symanzik; equation; callan symanzik equation; coleman; weinberg; model; potential; effective; coleman-weinberg potential; beta function; beta; non abelian; gauge; non abelian gauge theory; non abelian gauge theories; qed; quantum electrodynamics; electrodynamics; qcd; quantum chromodynamics; chromodynamics;

   Abstract : Several different approaches to renormalization are studied. The Callan-Symanzik equation is derived and we study its beta functions. An effective potential for the Coleman-Weinberg model is studied to find that the beta function is positive and that spontaneous symmetry breaking will occur if we expand around the classical field.

6. 25. The Broken Tail On a Lizard

   University essay from Konstfack/Inredningsarkitektur & Möbeldesign

   Author : Mana Trio Flingdal; [2015]
   Keywords : ;

   Abstract : In this project I have investigated how a set of rules can be applied to a particular sight and program. Inspired by the rules of the ’divine ‘proportion I applied its system of repetition and algorithm in a particular site and created a bridge with a diverse program beyond the simple intention of bridging two ends.
