About Dirac Equation

  1. Feb 15, 2013 #1
    While studying the Dirac Equation, we come across the gamma matrices. Can we consider these matrices as the components
    of a 4-vector ?

    This is the defining condition for the Dirac matrices. It is not derived, because it is a definition. It is required to allow the factorisation of the Klein Gordon equation in the derivation of the Dirac equation.

    No, the Dirac matrices are the Clebsch-Gordan coefficients that couple the product of two Dirac spinors to form a 4-vector. The result ψγμψ is a 4-vector.
