Why is the helicity for a mass-less particle Lorentz invariant?

Result; now that photons are mass-less, their energy, momentum, speed, etc are no more variables, in the sense of arbitrariness.… Read more.

A very few particles (out of 1000s) are named after scientists, eg the so called mu meson was called a… Read more.
