Puzzles in $B$ physics
Abstract
Description
I discuss some puzzles observed in exclusive $B$ meson decays, concentrating on the large difference between the direct CP asymmetries in the $B^0\to π^\mp K^\pm$ and $B^\pm\to π^0 K^\pm$ modes, the large $B^0\toπ^0π^0$ branching ratio, and the large deviation of the mixing-induced CP asymmetries in the $b\to sq\bar q$ penguins from those in the $b\to c\bar c s$ trees.
