Three Type of CP Violation in B Decay

• CP Violation in Decay
• CP Violation in Mixing
• CP Violation in the Interference Between Decay
  With and Without Mixing

11
CP Violation in Decay
Not useful for neutrals No clear experimental
evidence
12
CP Violation in Mixing
Not so accurate

Decay Distribution
Experimental evidence is asymmetry oscillation in
different tagged decay distributions.
