Chapman, Daniel MolsonWe introduce the form of 3D Superspace as a Z2-graded Lie Algebra. A set of Superspace Algebras can be defined in this way, characterized by the number of supercharges, N. Superspace will then be coupled to a Yang Mills field, to create a covariant derivative algebra. Various constraints must then be implemented, for consistency and in order to form an irreducible representation of this algebra. An in-depth view into the well-known example of N = 2 will be given, as well as a comparison with the corresponding compactification of 4D N=1. Then, the theory will be expanded to N = 3 and N = 4, before attempting to generalize to arbitrary N. However, beyond N = 4, the theory is discovered to only be known to be consistent at N = 8. The corresponding 2-point superfield and component actions are shown, as a basis for later theoriesDissertationTheoretical PhysicsPhysicsOffshellSuperspaceSupersymmetrySuper Yang Mills
