예제(Exercise) 50 및 해설(Solution)

Show that the Dirac equation separates into independent 2×2 blocks in the Weyl representation (see Exercise 2.2.49) in the limit that the mass m approaches zero. This observation is important in the ultra relativistic regime where the rest mass is inconsequential, or for particles of negligible mass (e.g., neutrinos).
