Abstract:

We present evidence for the decay mode $\Lambda^{0}_{b} \to\Lambda^{+}_{c} \pi^{-}$ using $\sim 106$ pb$^{-1}$ of the Two Track Trigger (TTT) data stream. We observe $214 \pm 19(stat)$ events. We furthermore use this signal to measure $\left( \sigma_{\Lambda^{0}_{b}}(p_T > 6)/ \sigma_{\overline{B^{0}}}(p_T > 6)

\pm 0.22 \mbox{ } \mbox{(} \Lambda_{c}\; {\cal{B}} \mbox{)} $.
