"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. The tensor method for 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 an oral exam (TEN1; 3 hp).

Examination

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

The oral examinations will be based on students' performance and presentations during the seminars, which means that attendance (at least 75 %) is therefore mandatory.

Grading

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