Learning Objectives
Knowledge acquired: starting from a basic knowledge of classical mechanics and electrodynamics, non relativistic quantum mechanics and elements of special relativity, the student acquires a basic knowledge concerning the course content (see below)
Competence acquired: calculation of cross-section and mean life for elementary particle processes by means of the Feynman’s diagrammatic technique and Feynman’s rules. Regularization of divergent integrals and renormalization.
Skills acquired (at the end of the course):
Dyson’s expansion and propagator (Green’s functions). Spontaneous symmetry breaking and connection with phase transitions. Low energy effective theories.
