Dive into the world of Quantum Chromodynamics (QCD) spectroscopy with this comprehensive lecture, the first of a two-part series. Explore the fundamental principles and latest developments in this crucial field of particle physics, as presented by Dr. Andrew Jackura. Gain insights into the study of hadron spectra and their properties, understanding how QCD governs the strong interactions between quarks and gluons. Learn about the theoretical frameworks and experimental techniques used to investigate the rich spectrum of particles predicted by QCD, including exotic states and glueballs. This in-depth talk provides a solid foundation for both students and researchers interested in the fascinating realm of subatomic particles and their interactions.
