B0ωη()andϕη(

Abstract: We calculate the branching ratios and CP-violating asymmetries for B 0 → ωη, ωη ′ , φη and φη ′ decays in the perturbative QCD (pQCD) factorization approach. The pQCD predictions for the CP-averaged branching ratios are Br(B 0 → ωη) = 2.7 +1.1 −1.0 × 10 −7 , Br(B 0 → ωη ′ ) = 0.75 +0.37 −0.33 × 10 −7 , and Br(B 0 → φη) = 6.3 +3.3 −1.9 × 10 −9 , Br(B 0 → φη ′ ) = 7.3 +3.5 −2.6 × 10 −9 which are consistent with currently available experimental upper limits. The inclusion of the gluonic contribution can change … Show more

“…We also give the predictions on the sum of the CP-averaged branching ratios of B0 → π − ρ + and B0 → π + ρ − and the other three B (s) decays in table I and table VI. In order to compare with QCDF approach [10,41,42,43,44,45] and PQCD approach [46,47,48,49,50,51,52,53,54,55,56,57,58], we also collect their results in these tables, together with the experimental data available at HFAG [39].…”

“…The first kinds of uncertainties are from uncertainties in charming penguins and gluonic form factors as discussed in the text; the second kinds of uncertainties are from those in the CKM matrix elements. We also cite the experimental data and theoretical results given in QCDF [10] and PQCD [46,52,54,57] approach to make a comparison. −0.17−0.07 b For B → ρη decays, there are two different predictions given in Ref.…”
