Particle Physics and Early Universe

Vak
2024-2025

Admission Requirements

Bachelor of Physics with the course Physics of Elementary Particles or a clear equivalent. Recommended Origin and Structure of the Standard Model and Origin and Evolution of the Universe

Description

This course will discuss how particle physics defines physics of the early universe, the subsequent cosmological scenario and the current state of the universe. Starting with basics of the Standard Model of particle physics (SM), we will see how the whole intricate structure of this theory exhibits itself in a hot and dense, quickly expanding universe. We will demonstrate that this allows to use astrophysical and cosmological observational data to check the SM. The next part will discuss the shortcomings of the Standard Model and different approaches to resolve them, as well as implications of this beyond the SM physics for the early universe (most importantly: the nature of dark matter, dark energy, mechanisms of baryogenesis and inflation).

Topics:

  • Primoridal nucleosynthesis and big bang theory

  • Neutrinos in the early univrese and relic neutrinos at present epoch

  • Dark matter: evidence, DM particles, massive neutrinos as dark matter.

  • Neutrino masses, mixing angle, CP violation

  • DM as beyond the SM physics. Possible properties of non-SM DM particles: WIMPs, super-WIMPs, axions

  • Basic ideas of effective field theory and the structure of the Standard Model of particle physics.

  • Neutrino masses as BSM physics

  • The problem of baryogenesis. Baryogenesis as a beyond SM phenomenon

  • An overview of various beyond SM scenarios and their implications for cosmology.

Course objectives

The course will give an overview of cosmological observations, which are interested for particle physics. Students will obtain practical knowledge in relativistic quantum mechanics, BBN, neutrino physics, dark matter properties calculation.

Transferable skills

You will be able to

  • learn to make a relation between mathematical models and physical systems, in both directions

  • improve you skills of planning time for doing weakly assignments

Timetable

Physics Schedule
For detailed information go to Timetable in Brightspace

In MyTimetable, you can find all course and programme schedules, allowing you to create your personal timetable. Activities for which you have enrolled via MyStudyMap will automatically appear in your timetable.

Additionally, you can easily link MyTimetable to a calendar app on your phone, and schedule changes will be automatically updated in your calendar. You can also choose to receive email notifications about schedule changes. You can enable notifications in Settings after logging in.

Questions? Watch the video, read the instructions, or contact the ISSC helpdesk.

Note: Joint Degree students from Leiden/Delft need to combine information from both the Leiden and Delft MyTimetables to see a complete schedule. This video explains how to do it.

Mode of instruction

Assessment method

Homeworks – 40%
Written exam – 60%
Final grade is a sum of grades for the homeworks and exam.
Exam can be retaken

Reading list

Registration

As a student, you are responsible for enrolling on time through MyStudyMap.

In this short video, you can see step-by-step how to enrol for courses in MyStudyMap.
Extensive information about the operation of MyStudyMap can be found here.

There are two enrolment periods per year:

  • Enrolment for the fall opens in July

  • Enrolment for the spring opens in December

See this page for more information about deadlines and enrolling for courses and exams.

Note:

  • It is mandatory to enrol for all activities of a course that you are going to follow.

  • Your enrolment is only complete when you submit your course planning in the ‘Ready for enrolment’ tab by clicking ‘Send’.

  • Not being enrolled for an exam/resit means that you are not allowed to participate in the exam/resit.

Remarks

Software
Starting from the 2024/2025 academic year, the Faculty of Science will use the software distribution platform Academic Software. Through this platform, you can access the software needed for specific courses in your studies. For some software, your laptop must meet certain system requirements, which will be specified with the software. It is important to install the software before the start of the course. More information about the laptop requirements can be found on the student website.
