some inquiries
1. Is it possible parity being violated by the weak force is because of further symmetry breaking of SU(2)xU(1) (besides the higgs field) ? Any papers about this?
2. I read in wiki that that mirror matter can recover the symmetry. What else (beside mirror matter) could restore the symmetry as it doesn't make sense something could be violated in a perfect gauge symmetry.
3. Lastly. If there were mirror matter.. Has anyone tried to tweak it so it can be used possible solution to the Hierarchy Problem... the mirror matter able to cancel some quantum contributions to avoid turning Higgs mass to Planck mass? In the following:

"• If you want to retain naturalness, then given that the LHC has indeed found
a seemingly fundamental lightish Higgs, you are pushed to invoke some
kind of heavy partners of SM particles to cancel the apparent quadratic
sensitivity to the cut-off
• Thus:
• SUSY (partners have different spin, symmetry enforces cancellations)
• Little Higgs (partners have same spin, symmetry enforces cancellations)
• Lee-Wick SM (partners have same spin but are kinetic ghosts)"
4. Could mirror matter be made into kinetic ghosts?
