    • Abstract

       

      I discuss some puzzles observed in exclusive B-meson decays, concentrating on the large difference between the direct CP asymmetries in the B0 → πK= and B± → π0K± modes, the large B0 → π0π0 branching ratio, and the large deviation of the mixing-induced CP asymmetries in the bsqq penguins from those in the bccs trees.
