| The aim of the course is to give systematic description of the basic types of interactions between elementary particles and experimental methods for their investigation. The bases of the kinematics of the elementary particles are presented. The different types of symmetry (continuous and discrete, spatial and internal, global and local) of the fundamental interactions and the corresponding conservation laws are considered. Classification of the elementary particles is given. The interactions are described in terms of local (gauge) groups of symmetry. Experimental methods in Elementary Particle Physics are subject to a special attention. A description of the strong interaction is given. The quark model of hadrons and the basic ideas of QCD are presented. The experimental indications for existence of quarks and gluons are discussed. Special attention is paid to the weak interaction. Lepton and quark currents, quarks mixing, CP violation in weak interaction, interactions carried by neutral currents are considered. The problem with mass and oscillations of neutrino are discussed. Glashow-Weinberg-Salam model for electromagnetic and weak interactions is presented. The attempts for construction of Grand Unified Theory of electromagnetic, weak and strong interactions are briefly discussed. Recent experiments verifying this models are examined. The basic problems and directions of development of Elementary Particle Physics are traced out. |
