Description
In this work, we investigate the hadronic loop contributions to the Υ(6S) → χbJφ (J = 0, 1, 2) along with Υ(6S) → χbJω (J=0, 1, 2) transitions. We predict that the branching ratios of Υ(6S) → χb0φ, Υ(6S) → χb1φ and Υ(6S) → χb2φ are (0.68-4.62) x 10-6, (0.50-3.43) x 10-6 and (2.22-15.18) x 10-6, respectively, and those of Υ(6S) → χb0ω, Υ(6S) → χb1ω and Υ(6S) → χb2ω are (0.15-2.81) x 10-3, (0.63-11.68) x 10-3, and (1.08-20.02) x 10-3, respectively. Especially, some typical ratios, which reflect the relative magnitudes of the predicted branching ratios, are given, i.e., for Υ(6S) → χbJφ transitions, Rφ10 = B[Υ(6S) → χb1φ]/B[Υ(6S) → χb0φ] ∼ 0.74, Rφ20 = B[Υ(6S) → χb2φ]/B[Υ(6S) → χb0φ] ∼ 3.28, and Rφ21 = B[Υ(6S) → χb2φ]/B[Υ(6S) → χb1φ] ∼ 4.43, and for Υ(6S) → χbJω transitions, Rω10 = B[Υ(6S) → χb1ω]/B[Υ(6S) → χb0ω] ∼ 4.11, Rω20 = B[Υ(6S) → χb2ω]/B[Υ(6S) → χb0ω] ∼ 7.06, and Rω21 = B[Υ(6S) → χb2ω]/B[Υ(6S) → χb1ω] ∼ 1.72. With the running of BelleII in the near future, experimental measurement of these two kinds of transitions will be a potential research issue. (orig.)
