Measurements of the branching fractions , and
Abstract
Using the data sample of of on-resonance data taken by the Belle detector at the KEKB asymmetric-energy electron-positron collider, we present the first measurements of branching fractions of the decays , , and . The signal yields for these decays are extracted from the recoil mass spectrum of the system recoiling against baryons in selected candidates. The branching fraction of is measured to be , where the first uncertainty is statistical and the second is systematic. The 90% credibility level upper limits on and are determined to be and , respectively.

abstractNote = {Using the data sample of 711 fb-1 of γ(4S) on-resonance data taken by the Belle detector at the KEKB asymmetric-energy electron-positron collider, we present the first measurements of branching fractions of the decays B-→Λ¯c-Ξc'0, B-→Λ¯c-Ξc(2645)0, and B-→Λ¯c-Ξc(2790)0. The signal yields for these decays are extracted from the recoil mass spectrum of the system recoiling against Λ¯c- baryons in selected B- candidates. The branching fraction of B-→Λ¯c-Ξc(2790)0 is measured to be (1.1±0.4±0.2)×10-3, where the first uncertainty is statistical and the second is systematic. The 90% credibility level upper limits on B(B-→Λ¯c-Ξc'0) and B(B-→Λ¯c-Ξc(2645)0) are determined to be 6.5×10-4 and 7.9×10-4, respectively.},
