I think this corresponds to what I've written about massless particles in my first post. If you start with an eigenspinor of \gamma^5 it stays an eigenspinor under proper orthochronous Lorentz transformations and therefore also under simple spatial boosts. So far everything is clear. This...

Hi folks, I've been reading into the concepts of chirality & helicity and often I find a statement that chirality is Lorentz invariant in contrast to helicity (which of course depends on the frame). BUT I don't see in which way chirality IS Lorentz invariant. For massless particles things...

Thanks a LOT, dude, this paper just really helped me! Good thing that the internet doesn't forget so even such old threads can be helpful.
