PHYS 5325 introduces students to the fundamental constituents of matter and the fundamental forces of nature. Key topics include: Overview of Particles and Forces: Understanding the basic building blocks of matter and the interactions between them. Particle Detectors and Accelerators: Exploring the tools and technologies used to detect and study elementary particles. Invariance Principles and Conservation Laws: Examining the symmetries and conservation laws that govern particle interactions. The Standard Model: Studying the theoretical framework that describes the electromagnetic, weak, and strong nuclear interactions. Electromagnetic, Weak, Strong, and Unified Interactions: Analyzing the fundamental forces and their unification.
