Right handed particles and SU(2)L gauge invariance

  1. Mar 7, 2012 #1
    If only left handed fields couple in the weak force, and we can boost to a frame that changes left handed fields to right handed ones, how can that theory be relativistically invariant?

    thanks for the help!

    Left-handed refers to chirality, not helicity.

    I read that chirality cannot be measured because it does not commute with H.
    It seems strange to say that it is left only because it interacts.
    Can you elaborate?
