IV.R145 — Homochirality and parity violation

Homochirality of terrestrial life (L-amino acids, D-sugars) has a structural origin: the crossing generator omega couples the two T^2 orientations (gamma,eta) vs (eta,gamma) with asymmetry inherited from A-sector parity violation, providing a tiny energetic enantiomer preference amplified over geological time by autocatalytic feedback.
