A Chiral symmetry

  1. Mar 7, 2016 #1
    Dear all
    Do we have chiral symmetry for weak interaction? I know that weak interaction is chiral.
    thank you

    It's even local chiral symmstry!

    Note a common confusion about chiral theories. This a theory which differentiates between left and right handed particles.

    In QED and QCD, the couplings to left and right handed fermions are identical. This is an example of a non-chiral theory.
