"Theoretical Particle Physics" will give the students fundamental
knowledge about the systematics and reactions of particles within the
framework of the so-called Standard Model.

Aim

After completion of the course you should be able to:

know and describe the standard model of particle physics.

compute decay rates and cross-sections with help of relativistic kinematics.

use symmetries to restrict the form of the S-matrix, for example, isospin, discrete symmetries, and spacetime symmetries.

give an account of and describe the static properties of the hadrons from the quark model.

know the basic principles of the electroweak theory.

have knowledge about how deep inelastic scattering shows the existence of quarks in the nucleons.

know about basic neutrino physics and describe neutrino oscillations.

Syllabus

Introductory survey. Conservation laws. Basic reaction theory. Feynman
diagrams. Lorentz invariance. One particle states. Binary
reactions. Determination of mass. Scattering theory (the S-matrix,
decay rate, scattering
cross-section). Symmetries. Time-reversal. Space-reflection. Charge
conjugation. Determination of spin and parity of
particles. Isospin. Strangeness. The quark model. Color. Hadron
spectroscopy. Quarkonium. Electroweak interaction of quarks. The Higgs
mechanism. Deep inelastic scattering. Neutrino physics. Neutrino
oscillations.

Hand in assignments (INL1; 4.5 hp) and a theory exam (TEN1; 3 hp).

Examination

The examination of the course will be a combination of homework problems and a theory exam. There will be three mandatory sets of homework problems during the course. These will be distributed and should be handed in according to the following scheme:

The theory exam will be based on the student's performance during the seminars, which means that attendance (at least 5 out of 7 seminars) is therefore mandatory.
In order to have a reasonable discussion going in the seminars, the students are required to study the relevant course material before the seminars. This will be checked through a quiz given during the first 5 minutes of the seminar.
In order to have attendance registered, at least one answer out of three must be correct.
In addition, all seminars will end with a quiz that counts for the theory exam. Each quiz will consist of three questions, which means that there will be in total 21 questions. In order to pass the theory exam, you will need at least 14 correct answers on the questions in the quizzes.
All quiz questions are randomly chosen from a pool of questions related to the particular seminar and any particular question may appear in both the pre-quiz and the post-quiz.

Grading

The different grades are: A, B, C, D, E, Fx, and F. The grades will be awarded according to the following scheme:

Homework problems (INL1)

Grade

Homework problems

F

< 40% of all problems correct

E

≥ 40% of all problems correct

D

≥ 60% of all problems correct

C

≥ 70% of all problems correct

B

≥ 80% of all problems correct

A

≥ 90% of all problems correct

In addition, you need to obtain at least 40 % on each homework problem set in order to obtain a passing grade (E or higher). If you obtain a total result of more than 40 %, but do not fulfill this criterion, you will be given the grade Fx and a chance to make a completing task for the grade E.

Seminars (TEN1)

The seminars are graded P (pass) or F (fail). In order to obtain a P, you need to attend at least 5 out of 7 seminars and score at least 14 out of 21 points on the quizzes at the end of the seminars (see the subsection "Examination" for details).

Final grade

When you have passed both parts of the course (INL1 and TEN1), you will obtain a final grade. The final grade will be the same as your grade on the homework problems (INL1).
For PhD students, the different grades are: P (pass) and F (fail).
