Weba symmetry: explicit breaking, spontaneous breaking, and finally anomalous breaking. In this part of the lectures we will concern ourselves with the first two types of breakings of the so-called chiral symmetry, the exact meaning of which will become clear later. We will come to the anomalous symmetry breaking towards the end of the course.
