Objectives and competences

Students learn about the basic laws of nuclear and particle physics.
Subject-specific competencies: knowledge and understanding of the interactions of elementary particles and their bound states (hadrons); the ability to solve practical problems in these areas; the ability to link the theoretical predictions and measurements; critical evaluation and application of new knowledge in the field of nuclear and particle physics.

Intended learning outcomes

Knowledge and understanding:
Acquire basic knowledge on theories and experiments in nuclear and particle physics. The ability to link the theoretical predictions and measurements. Critical assessment and application of new knowledge in the field of nuclear and particle physics.
Application:
Understanding of the laws of modern physics and applications of mathematical approaches.
Reflection:
A critical assessment of the theoretical predictions with the results of the measurements
Transferable skills:
Ability to understand the phenomena and the interpretation and evaluation of the results of measurements

Assessment

2 tests with problem solving, written exam (problem solving)
Oral exam (questions from lectures)
grading: 5 (fail), 6-10 (pass) (according to the Statute of UL)
