Search for the decay ${\overline B}^{0}\rightarrow{\Lambda_{\rm c}^{+}}{\overline p}{p}{\overline p}$

N. Arnaud

Abstract

We report a search for the decay ${\overline B}^{0}\rightarrow{\Lambda_{\rm c}^{+}}{\overline p}{p}{\overline p}$. Using a data sample of $471 \times 10^6\: B{\overline B}$ pairs collected with the BABAR detector at the PEP2 storage ring at SLAC, we find no events and set an upper limit on the branching fraction ${\cal B}({\overline B}^{0}\rightarrow{\Lambda_{\rm c}^{+}}{\overline p}{p}{\overline p}) \times\frac{{\cal B}(\Lambda_{\rm c}^{+}\rightarrow p K^{-} \pi^{+})}{0.050} < 2.8\times10^{-6}$ at $90\,\%$ CL, where we have normalized ${\cal B}(\Lambda_{\rm c}^{+}\rightarrow p K^{-} \pi^{+})$ to the world average value.
