Is Chiral Symmetry Present in Weak Interaction?

[shereen1]

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.
