Chirality and Eliticity in Dirac Equation

This lecture delves into the concepts of chirality and elicity in the Dirac equation, exploring the relationship between left and right spinors, Lorentz invariance, and the massless limit. The instructor explains the significance of gamma 5 matrix, projectors, and the distinction between left and right components. The lecture also covers the orthogonality of solutions, completeness relations, and the quantization process, providing a comprehensive understanding of these fundamental concepts in relativistic quantum mechanics.
