CP nonconservation at the unification scale

The three-generation phase invariant measure of CP nonconservation is shown to satisfy a simple and solvable renormalization-group equation. Its value falls by 4 to 8 orders of magnitude between the weak and grand unification scales in the standard model, as well as in its two Higgs and supersymmetr...

Zusammenfassung:	The three-generation phase invariant measure of CP nonconservation is shown to satisfy a simple and solvable renormalization-group equation. Its value falls by 4 to 8 orders of magnitude between the weak and grand unification scales in the standard model, as well as in its two Higgs and supersymmetric extensions. Such a small value of CP nonconservation at the grand unification scale can pose a problem for baryogenesis; this is avoided if there are heavy quarks with masses close to their fixed points.
