Search for the decay ${\overline{B}}^0\to {\Lambda }_{\mathrm{c}}^{+}\overline{p}p\overline{p}$

Abstract

We report a search for the decay ${\overline{B}}^0\to {\Lambda }_{\mathrm{c}}^{+}\overline{p}p\overline{p}$. Using a data sample of $471\times 10^{6}B\overline{B}$ pairs collected with the BABAR detector at the PEP-II storage ring at SLAC, we find no events and set an upper limit on the branching fraction $\mathcal{B}({\overline{B}}^0\to {\Lambda }_{\mathrm{c}}^{+}\overline{p}p\overline{p})\times \frac{\mathcal{B}({\Lambda }_{\mathrm{c}}^{+}\to p{K}^{-}{\pi }^{+})}{0.050}<2.8\times 10^{-6}$ at $90$ C.L., where we have normalized $\mathcal{B}({\Lambda }_{\mathrm{c}}^{+}\to p{K}^{-}{\pi }^{+})$ to the world average value.
