Description
Prof. Janusz Gluza, Prof. Jan Kisiel
In the first part of the lecture the following will be discussed: the structure of the atomic nucleus (including the Rutherford experiment), nuclear decay (including natural radioactivity, i.e., the one around us), the interaction of nuclear radiation with matter (including their use for particle detection) and the basis of nuclear reactions. The lecture will end with a presentation of 2-3 selected contemporary experiments in particle physics. Afterwards, the concept of lepton numbers and the theoretical basis of its introduction related to massive neutrinos will be discussed. The processes that break the lepton number will be considered in the context of the phenomenon of neutrino oscillations and processes which take place both at low energies (e.g. neutrinoless double beta decay) and high energies (e.g. proton-proton collisions with Majorana neutrinos).
