The weak interaction

Particle Physics 2: Standard Model (Winter, 2010)

February 15, 2010

In this lecture Professor Susskind continues with the weak interaction, answering the question "Why is the weak force weak?" He connects this to the form of the propagator in Feynman diagrams. The lecture ends with the introduction of explicit and spontaneous symmetry breaking.
