Osaamistavoitteet

At the end of this course, students will be able to use the terminology and concepts of particle physics, the Standard Model in particular. Students will be able to apply relativistic kinematics in various collision systems and apply the symmetry principle and conservation laws in finding the quantum numbers (spin, parity, C-parity, isospin) of particles in scattering and decay processes. They will be able to couple together different types of angular momenta or isospin operators and apply the resulting quantum number systematics and find the equations of motion of a theory, based on Euler-Lagrange equations as well as solve simple group-theory problems, do calculations in e.g. the SU(2) and SU(3) groups. They will also be able to find the solutions of the Klein-Gordon equation and Dirac equation of relativistic quantum mechanics derive the Lagrange densities of QED, QCD and electroweak unification theory on the basis of local gauge symmetry and apply the idea of spontaneous symmetry breaking and Higgs mechanism in different theories. In addition, they will be able to compute scattering cross sections and decay widths with Feynman rules in leading-order perturbation theory of QED, QCD, and electroweak unification theory and explain the purpose and arrangement of particle detectors e.g. at the LHC.
