Learning outcomes This UC aims to provide students with a working knowledge of Lie groups and algebras
and gauge theories in general, and the Standard Model and important current research paths for its
necessary extension.
The approach is designed to prepare students to develop research papers on models and
phenomenology of High Energy Physics.
At the end of this UC the student should:
- know Lie groups and algebras, with an emphasis on their most relevant representations for
gauge theories;
- understand the construction, quantization and tools for calculating non-abelian gauge theories with
spontaneous symmetry breaking;
- know the Standard Model and its phenomenology;
- understand the need to go beyond the Standard Model and some of the most important directions of research;
- be able to tackle problems, deepen knowledge and explore the literature independently.
