Particle Notes
... We can see right away that in the limit |~p | → 0, solutions have E = ±m. Does this mean that the Dirac Equation has negative energy solutions?! No. We interpret the “negative energy solutions” as antiparticles with positive energy. Antiparticles are like their corresponding particles with all signs ...
