Physics 222 UCSD/225b UCSB Lecture 7 Mixing & CP violation (3 of 3) Today, we focus on how to measure things, and what the present knowledge is from the combination of theory and experiment.

Heavy Quark Symmetry predicts that the B -> D* transition in B -> D* l nu has trivial form factor for the part of phase space when the D* is at rest in the B restframe. However, this also leads to minimal pT for the slow pion in the D* -> D pi decay. |Vcb| is theoretically most accurately extracted from experimental data where it is experimentally most difficult.

interferes with b -> c transition, IFF one chooses a decay of the D meson that is common for D and anti-D meson. The resonance structure then provides the CP conserving phase analyzer to measure gamma from the interference. B : D K S0 + Poluektov @ EPS09 B + : D K S0 +
