Learning Objectives
- NUCLEAR AND PARTICLE PHYSICS I
Our current understanding of the sub-atomic Universe is based on a number of profound theoretical ideas that are embodied in the Standard Model of particle physics. However, the development of the Standard Model would not have been possible without a close interplay between theory and experiment. Starting from the first evidence of the nuclear structure, the course aims to discuss our current understanding of Particle Physics.
