Wk 5: Just what does CP violation really mean?


Anti-matter: Mirror of the Universe
According to Wikipedia, CP is ”the product of two symmetries: C for charge conjugation, which transforms a particle into its antiparticle, and P for parity, which creates the mirror image of a physical system.”  CP Violation is the breaking of the CP law due to decay of kaons, the ‘short-lived mesons that decay into simpler particles’, in ‘slightly different modes than expected’.  This apparently accounts for why there is not a 50/50 balance of matter and anti-matter in the Universe; which is a good thing, because scientists postulate they would destroy each other, and us with it.
