Explore the fundamental principles of nuclear interactions through an in-depth lecture on effective field theory. Delve into the complexities of nuclear physics as Professor Luca Girlanda presents the first installment of his series on the effective field theory approach to understanding nuclear interactions. Over the course of 1 hour and 45 minutes, gain valuable insights into this powerful theoretical framework that has revolutionized our understanding of nuclear forces. Examine how effective field theory provides a systematic and model-independent description of low-energy nuclear phenomena, bridging the gap between quantum chromodynamics and nuclear physics. Discover the key concepts, mathematical formulations, and practical applications of this approach in nuclear research and beyond.
