Evidence for the baryonic decay ${\overline{B}}^{0}\to {D}^{0}\mathrm{\Lambda }\overline{\mathrm{\Lambda }}$
Evidence is presented for the baryonic B meson decay B¯0→D0ΛΛ¯ based on a data sample of 471×106 BB¯ pairs collected with the BABAR detector at the PEP-II asymmetric e+e− collider located at the SLAC National Accelerator Laboratory. The branching fraction is determined to be B(B¯0→D0ΛΛ¯)=(9.8+2.9−2....

Evidence is presented for the baryonic B meson decay B¯0→D0ΛΛ¯ based on a data sample of 471×106 BB¯ pairs collected with the BABAR detector at the PEP-II asymmetric e+e− collider located at the SLAC National Accelerator Laboratory. The branching fraction is determined to be B(B¯0→D0ΛΛ¯)=(9.8+2.9−2.6±1.9)×10−6, corresponding to a significance of 3.4 standard deviations including additive systematic uncertainties. A search for the related baryonic B meson decay B¯0→D0Σ0Λ¯ with Σ0→Λγ is performed and an upper limit B(B¯0→D0Σ0Λ¯+B¯0→D0ΛΣ¯0)<3.1×10−5 is determined at 90% confidence level. |
