             The goal of the course is to give systematical description of fundamental interactions of elementary particles and methods for their experimental investigation. An introduction in the relativistic kinematics and formalism for calculation of the cross sections of the elementary particles interactions are given. The different types of symmetry ( discrete and continuous, spatial and internal, global and local (gauge) ) of fundamental interactions and corresponding conservation laws are considered. A classification of elementary particles is presented. Their interactions are described in the framework of gauge field theories. The experimental methods used in today elementary particle physics are considered. The description of strong interactions starts with quark-parton model of hadrons. The basic concepts of Quantum Chromodynamics and experimental indications for existence of quarks and gluons are presented. Detailed description of weak interactions including CP-violation, neutral currents and neutrino oscillations is given.The Weinberg-Salam model of electroweak interactions is discussed. An introduction to the models giving an unified description of strong and electroweak interactions (GUT) is given. The results of experimental tests of the Standard Model of the electroweak and strong interactions are presented.
To attend this course a basic knowledge on Quantum Mechanics, Quantum Field Theory and Group Theory is required.
