概要 | K.Abe,S.Okuno,et al.[Belle Collaboration],The B meson decay modes B → Dp{p} and B → D*p{p} have been studied using 29.4fb-1 of data collected with the Belle detector at KEKB. The {B}0 → D0p{p} and {B}0 → D*0p{p} decays have been observed for the first time with branching fractions B({B}0 → D0p{p}) = (1.18±0.15±0.16)×10-4 and B({B}0 → D*0p{p}) = (1.20-0.29+0.33±0.21)×10-4. No signal has been found for the B+ → D+p{p} and B+ → D*+p{p} decay modes, and the corresponding upper limits at 90% C.L. are presented. |
