CP Violation in the B System<br />
“You can never tell with bees.”<br />
A.A. Milne, Winnie-the-Pooh<br />
The B 0 - B 0<br />
system is an excellent probe <strong>for</strong> CP violation studies.<br />
◆ Large CP violation expected in many channels.<br />
◆ “Gold-plated” channels exist with clean theoretical predictions and<br />
clean experimental signatures.<br />
The goal: Make enough independent measurements <strong>of</strong> CP violating<br />
effects to over-constrain the Standard Model.<br />
◆ NB: there is only one origin <strong>of</strong> CP violation in the SM.<br />
Two possible outcomes:<br />
◆ Everything is consistent and fully determines the CKM parameters.<br />
→ CP violation is fully explained by the SM.<br />
◆ No single choice <strong>of</strong> CKM parameters is possible.<br />
→ New physics beyond the SM.<br />
