Abstract
We predict the rates of the charmless three-body B0 → ρ -pn̄ and π-pn̄ modes due to weak vector current contributions to be ∼ 4 × 10-6 and 2 × 10-6, respectively. The basis is a factorization approach of current produced nucleon pairs, together with an isospin transformation that relates nucleon weak vector form factors to electromagnetic form factors. Adding the axial vector current contribution, we find B0 → ρ-pn̄ and B+ → ρ0 pn̄ to be at 10-5 order. The three-body modes appear to dominate over the two-body modes such as B → p p̄, pΛ. © 2002 Elsevier Science B.V. All rights reserved.
