Title: Measurements of the branching fractions B(B- Λ ¯ c - Ξ c ' 0 ) , B(B- Λ ¯ c - Ξ c (2645)0) and B(B- Λ ¯ c - Ξ c (2790)0)

Abstract

Using the data sample of 711 fb - 1 of γ ( 4 S ) 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 - Ξ c ' 0 , B- Λ ¯ c - Ξ c (2645)0 , and B- Λ ¯ c - Ξ c (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 - Ξ c (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 - Ξ c ' 0 ) and B(B- Λ ¯ c - Ξ c (2645)0) are determined to be 6.5×10 - 4 and 7.9×10 - 4 , respectively.
