Recommended Prerequisites

Quantum Mechanics I and II, Foundations of Modern Physics.

Teaching Methods

- Lectures using mainly the blackboard, but also with presentations and computer animations, with exposure of concepts and fundamental theories, and discussion of practical applications of these concepts.
- Problem solving classes with typical examples of the subjects under study;
- Development of projects with broader scope and greater depth than the typical examples and problems.

Learning Outcomes

- The student should learn the symmetry laws of elementary processes and the properties of the fundamental interactions.
- Should know the main features of the Standard Model of Particle Physics, the experimental observations that support it and its limitations.
- Understand the concept of cross-section and its importance. Learn how to compute cross-sections at leading order using Feynman rules.
- Know the most important experiences of High Energy Physics (HEP), theirs purposes and main results obtained.
- knowledge about the different types of particle accelerators.
- Acquire skills in analyzing and solving problems.
