Abstract / Description:We report the first observation of the decays $B^0 \\rightarrow p\\bar{\\Lambda} D^{(*)-}$. The data sample of $711$ fb$^{-1}$ used in this analysis corresponds to $772$ million $B\\bar{B}$ pairs, collected at the $\\Upsilon(4S)$ resonance by the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. We observe $19.8\\sigma$ and $10.8\\sigma$ excesses of events for the two decay modes and measure the branching fractions of $B^0 \\rightarrow p\\bar{\\Lambda} D^{-}$ and $B^0 \\rightarrow p\\bar{\\Lambda} D^{*-}$ to be $(25.1\\pm2.6\\pm3.5)\\times10^{-6}$ and $(33.6\\pm6.3\\pm4.4)\\times10^{-6}$, respectively, where the first uncertainties are statistical and the second are systematic. These results are not compatible with the predictions based on the generalized factorization approach. In addition, a threshold enhancement in the di-baryon ($p\\bar{\\Lambda}$) system is observed, consistent with that observed in similar $B$ decays.
