This chapter discusses the physics of quantized Dirac fields with detailed treatment of Dirac equation, representations of gamma matrices, products of gamma matrices, relativistic covariance (boosts, rotations, and invariants), helicity, gauge transformations, chirality, solution of the Dirac equation (Dirac representation, chiral representation, two-component helicity eigenstate spinors, and massless field), quantization, symmetry transformation of states (space-time translations and Lorentz transformations), C, P, and T transformations, wave packets, and Fierz transformations.
