Prerequisites

It is recommended to have followed the courses Introduction to Quantum Field Theory, Advanced Quantum Field Theory and Standard Model: Fundamentals and Phenomenology.


Objectives and Contextualisation

The main purpose of this course is to give an overview of the possible new physics scenarios that could lie beyond the Standard Model of particle physics. This new physics is necessary to overcome certain drawbacks of the SM.


Competences

  • Formulate and tackle problems, both open and more defined, identifying the most relevant principles and using approaches where necessary to reach a solution, which should be presented with an explanation of the suppositions and approaches.
  • Understand the bases of advanced topics selected at the frontier of high energy physics, astrophysics and cosmology and apply them consistently.

Learning Outcomes

  1. Critical analyse the different extensions to the standard model proposed.
  2. Distinguish between the different solutions to the problems of hierarchy in the standard model.
  3. Understand the problems of the standard model and the need to go beyond it.

Content

BMS1: Before the SM:
— Criteria for building models for particle physics: Effective Field Theories (EFT) and first applications
— Accidental symmetries, consistency of the EFT, no-lose theorems for discovery & naturalness issues
BSM2: Behind the SM:
— The SM as an EFT and theoretical reasons for improvement
— Unexplained experimental evidences
BSM3: Beyond the SM:
— Towards the reduction of parameters: Grand Unified Theories (charge quantization & gauge-coupling unification)
— Addressing the unnaturalness of the SM: Proposals for the strong CP problem (axions) and hierarchy problem (compositeness and supersymmetry)


Activities and Methodology

Title Hours ECTS Learning Outcomes
Type: Directed      
Theory Lectures 45 1.8 1, 2, 3
Type: Supervised

Type: Autonomous      
Exercises 40 1.6 1, 2, 3

Attendance to theory lectures, exercises, and preparation of a topic related to the course (to be presented orally).

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.


Assessment

Continous Assessment Activities

Title Weighting Hours ECTS Learning Outcomes
Attendance to the lectures 20% 0 0 1, 2, 3
Development of a topic 40% 5 0.2 1, 2, 3
Exercises 40% 5 0.2 1, 2, 3

 Attendance to the lectures, exercises and develop a topic related to the course.

 There will be a recovery exam for students who have submitted the exercises but failed with a grade higher than 3.5.

 

 

 

 

This subject/module does not foresee the single assessment  system.
