Success of B FactoriesFirst precise test of KM picture for CPV.
sin2φ1= +0.726±0.037 is now a precise measurement (~5%). The other angles are being measured more seriously.
φ2 from Sρρ and ρπ Dalitz– 2φ1+φ3 from B D(*)π
φ3 from B DK (w/ D Dalitz)+ side measurements too.

Measurement of |Vub|
Inclusive b u l ν with fully reconstructed tag.
Mx, q2, P+
– Good determination of mb by b c l ν / b sγ is essential.
Exclusive B π l ν with full recon or D* l ν tagging.– High quality data in high q2
– Form factor by unquenched lattice D π l ν @ CLEO-c
~5% determination is possible.~5% determination is possible.
Extrapolation from present (Mx,q2) measurement.
