Abstract

We report improved measurements of the product branching fractions B(B+→D¯0Ds0∗+(2317))×B(Ds0∗+(2317)→Ds+π0)=(8.0-1.2+1.3±1.1±0.4)×10-4 and B(B0→D-Ds0∗+(2317))×B(Ds0∗+(2317)→Ds+π0)=(10.2-1.2+1.3±1.0±0.4)×10-4, where the first errors are statistical, the second are systematic and the third are from D and Ds+ branching fractions. In addition, we report negative results from a search for hypothesized neutral (z0) and doubly charged (z++) isospin partners of the Ds0∗+(2317) and provide upper limits on the product branching fractions B(B0→D0z0)×B(z0→Ds+π-) and B(B+→D0z++)×B(z++→Ds+π+) that are more than an order of magnitude smaller than theoretical expectations for the hypotheses that the Ds0∗+(2317) is a member of an isospin triplet. The analysis uses a 711fb-1 data sample containing 772 million BB¯-meson pairs collected at the γ(4S) resonance in the Belle detector at the KEKB collider.

N2 - We report improved measurements of the product branching fractions B(B+→D¯0Ds0∗+(2317))×B(Ds0∗+(2317)→Ds+π0)=(8.0-1.2+1.3±1.1±0.4)×10-4 and B(B0→D-Ds0∗+(2317))×B(Ds0∗+(2317)→Ds+π0)=(10.2-1.2+1.3±1.0±0.4)×10-4, where the first errors are statistical, the second are systematic and the third are from D and Ds+ branching fractions. In addition, we report negative results from a search for hypothesized neutral (z0) and doubly charged (z++) isospin partners of the Ds0∗+(2317) and provide upper limits on the product branching fractions B(B0→D0z0)×B(z0→Ds+π-) and B(B+→D0z++)×B(z++→Ds+π+) that are more than an order of magnitude smaller than theoretical expectations for the hypotheses that the Ds0∗+(2317) is a member of an isospin triplet. The analysis uses a 711fb-1 data sample containing 772 million BB¯-meson pairs collected at the γ(4S) resonance in the Belle detector at the KEKB collider.
