Puzzles in B physics
I discuss some puzzles observed in exclusive B-meson decays, concentrating on the large difference between the direct CP asymmetries in the B0 → π−K= and B± → π0K± modes, the large B0 → 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.
