Proposal to solve a few puzzles in semileptonic B decays

Abstract

We discussed the impact of the existence of B -> D' l nu decays to radially excited D' mesons on various long-standing puzzles in the experimental data of semileptonic b -> c ell nu decays, as summarized in our recent article arXiv:1202.1834, and updated some numbers.
