Jl. Diazcruz et al., ISOSPIN CORRECTIONS TO CHARMLESS SEMILEPTONIC B-]V TRANSITIONS, Physical review. D. Particles and fields, 54(3), 1996, pp. 2388-2390
We compute isospin corrections to the charmless semileptonic B-->V tra
nsitions arising from rho-omega mixing and discuss its relevance in th
e determination of V-ub.
