From neutrons to axions

Fundamental discrete symmetries: ? T: time reversal ? P: parity ? C: charge conjugation

CPT is a symmetry of local, hermitean Lorentz invariant theories;

C & P are individually maximally violated in weak interactions

CP is weakly violated in the weak interactions (K, B meson systems)

Additional CP violation a prerequisite for baryogenesis
