To reduce the dependence of the result on the form factor model, the measurement is performed over the entire q2 range. The resulting branching fractions are B(B+→ηâ "+νâ ")=(2.83±0.55(stat.)±0.34(syst.))×10-5 and B(B+→η′â "+νâ ")=(2.79±1.29(stat.)±0.30(syst.))×10-5.10 page(s)application/pdfenIn CopyrightPhysicsArticle - Refereedhttps://doi.org/10.1103/PhysRevD.106.0320131063Piilonen, Leo [0000-0001-6836-0748]2470-0029
