| Abstract: | I discuss some puzzles observed in exclusive B-meson decays, concentrating on the large difference between the direct CP asymmetries in the B
0 → π−
K
= and B
± → π0
K
± modes, the large B
0 → π0π0 branching ratio, and the large deviation of the mixing-induced CP asymmetries in the b → sqq penguins from those in the b → ccs trees. |
