Description

We report the first observation of the decay B0→Ds+Λp with a statistical significance of 6.6σ. We measure B(B0→Ds+Λp)=(2.9±0.7±0.5±0.4)x10-5, where the first error is statistical, the second is systematic, and the third error comes from the uncertainty in B(Ds+→φπ+). The data used for this analysis was accumulated at the Υ(4S) resonance, using the Belle detector at the KEKB asymmetric-energy e+e- collider. The integrated luminosity of the data sample is 414 fb-1, corresponding to 449x106 BB pairs
