Query: A proposal to solve some puzzles in semileptonic B decays   Some long-standing problems in the experimental data for semileptonic b -> c
l nu decay rates have resisted attempts to resolve them, despite substantial
efforts. We summarize the issues, and propose a possible resolution, which may
alleviate several of these tensions simultaneously, including the "1/2 vs. 3/2
puzzle" and the composition of the inclusive decay rate in terms of exclusive
channels.
