After a short introduction to the theoretical foundations and experimental tests of the standard model, supersymmetry, leptoquarks, and extra dimensions will be treated among other topics. Thereby the phenomenological aspect, i. e., the search for new particles and interactions at existing and future particle accelerators will play a significant role.
The goal of the lecture is the introduction into several theoretical concepts that provide solutions for the open questions of the Standard Model of particle physics and thus lead to physics beyond the Standard Model.
Besides the theoretical concepts the phenomenological aspect plays a role, i.e. the search for new particles and interactions at the existing and future particle accelerators plays a crucial role.
