Wess-Zumino-Witten Model

The Wess-Zumino-Witten (WZW) model is a mathematical framework used in theoretical physics to describe certain quantum systems with symmetries, particularly in particle physics and string theory. It captures how fields (which represent particles or strings) evolve and interact on two-dimensional surfaces, ensuring consistency and symmetry properties. The model incorporates an elegant term, the Wess-Zumino term, which accounts for quantum anomalies and topological features, making it crucial for understanding phenomena like conformal invariance and gauge symmetries. Overall, it combines geometry, topology, and quantum theory to help researchers explore fundamental forces and particles.
