Cosmic Variance: Marketing CP Violation
Sean discusses the recent CP violation results, and how they were reported.
The point is that the conclusion doesn’t hold — not everything about CP violation is necessarily related to baryogenesis. We don’t know how baryogenesis actually happened — there are many theories on the market, and any of them or none of them may be right. Therefore, there’s no way of knowing whether any particular manifestation of CP violation is in any way related to baryogenesis. There could be lots of different ways in which CP is violated. In particular, there’s no compelling theoretical reason why the CP violation being studied in the decays of B mesons has anything at all to do with baryogenesis. It’s possible — lots of things are possible. But what’s being studied isn’t baryogenesis; it’s CP violation.
Mea culpa. Ten 3-loop Feynman diagrams as penance.
Ten 3-loop Feynman diagrams? Physicists have much tougher penance than Catholics, it would appear.
All tests of vacuum isotropy employ photons or achiral atomic mass configurations, arxiv:0706.2031, 0905.1929, 0801.0287, 0912.5057. The screamingly obvious test has never been attempted, for physics boasts an illusion of knowledge that emergent phenomena cannot be fundamental: Do chemically and macroscopically identical, inverse geometric parity atomic mass distributions vacuum free fall identically?

Do opposite shoes violate the Equivalence Principle?
If space itself is intrinsically chiral, parity violations are the default. It is the parity-blind strong interactions that are the exceptions – as one would anticipate.
