"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 exams (read: oral exams) will take place after or around the last lecture of the course. Each exam will take approximately 20 minutes. The time for the exam will be agreed upon between the student and the lecturer, but the student is obliged to take contact with the lecturer.

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.

Theory exam (TEN1)

The theory exams are graded P (pass) or F (fail).

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).
