OVERVIEW

The course aims to deepen some of the topics that are at the heart of modern research in particle physics.

LEARNING OUTCOMES

The aim of the course is to present the basic analytical tools and the phenomenological bases of modern particle physics, through various examples and applications.

AIMS AND LEARNING OUTCOMES

• introducing basic tools to understand modern particle physics and the necessary pre-requisite to achieve an understanding of particle physics based on quantum mechanics and relativity
• introducing modern particle physics from a phenomenological viewpoint
• introducing to techniques and methods to study elementary particles’ properties and their interactions, with particular focus on the theory and phenomenology of strong interactions.
• discussing open problems in high-energy physics
• all topics are complemented by examples and applications

Teaching methods

Exam description

Written test with exercises aimed at verifying the concepts of the first part of the course. The oral exam instead consists of a discussion of the written test and an interview aimed at verifying the topics covered in the second part of the course.

Assessment methods

The written exam contains exercises both of a theoretical nature, aimed at verifying the comprehension of the arguments developed in class, and of applicative nature. In the latter case, the resolution of numerical problems aims to verify that the student is familiar with the concepts discussed in class and he/she can apply them to solve physical problems. The oral exam, of a duration of about 30 minutes, instead consists essentially in the exposition of one of the topics addressed during the study of strong interactions.
