Answer #1

Step 1-

In Physics, the Dirac equation is the one discovered by Pual Dirac and it is a relativistic wave equation.

Regarding the spin it is -1/2 for quarks and electrons.

Step 2-

In the context of quantum field theory of quantum, the Dirac equation is used to describe quantum fields corresponding to spin -1/2 particles.

Step 3-
