Hi, I'm recently reading an introductory text about particle physics and there is a section about the Dirac equation. I think I can understand the solutions for rest particles, but the plane wave solutions appear to be a bit weird to me. For instance, when the upper states are (1 0), the lower states are non zero. Does this mean that when the electron is moving, there is some component of it being a positron?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks!
