Abstract
In this master thesis the spacetime, global and gauge symmetries of the Standard Model are reviewed. These symmetries are used as a basis for finding possible extensions of this successful model, such as the two Higgs doublet model and Left-Right model. Methods of finding subgroups and the slitting up of representations are discussed based on Dynkin diagrams. These methods are applied to analyse the subgroups of the exceptional group E_6 as candidates for Grand Unified Theory groups. In this study SU(5), SO(10) and SU(3)^3 and SU(4) x SU(2) x SU(2) are most important. A phenomenological comparison between these models is given focussed on the different types of leptoquarks that could be responsible for the not yet observed proton decay.
