Main Question or Discussion Point
Hello! So Weyl spinors are 2 dimensional spinors which describe massless particles and have definite helicities. So if we have a right handed Weyl spinor going along the positive x-axis, it's spin will always point along the positive x-axis too. I am a bit confused how can an object have 2 spin states, yet it's spin can point only in a given direction. I guess I am missing something. Can someone explain to me how does this work?
