The goal of the lecture is the introduction into several theoretical concepts that provide solutions for the open questions of the Standard Model (SM) of particle physics and thus lead to physics beyond the Standard Model.

After a short introduction into the theoretical basics and experimental tests of the SM, grand unified theories, supersymmetry and hidden valley models will be treated among other topics beyond the SM. Besides the theoretical concepts the phenomenological aspects play a role, i.e. the search for new particles and interactions at the existing and future particle accelerators will be discussed in detail.

The theoretical concepts will be introduced by M. Spira. The experimental aspects of the search for new particles at different accelerators will be treated by A. de Cosa.

The lecture is recommended for students of experimental particle physics and should be attended in connection to the lecture 'Phenomenology of Particle Physics I und II'. But it is recommended as well to theoretical physics students interested in BSM phenomenology and a more broad education in BSM physics, where knowledge about quantum field theory will be needed as an alternative to 'Phenomenology of Particle Physics I und II'.
