Abstract

We report a search for the decay ${\bar{B}}^{0} \to Λ_{c}^{+} \bar{p} p \bar{p}$ . Using a data sample of $471 \times 1 0^{6}$ $B \bar{B}$ pairs collected with the BABAR detector at the PEP-II2 storage ring at SLAC, we find no events and set an upper limit on the branching fraction $B ({\bar{B}}^{0} \to Λ_{c}^{+} \bar{p} p \bar{p}) \times \frac{B (Λ_{c}^{+} \to p K^{-} π^{+})}{0.050} < 2.8 \times 1 0^{- 6}$ at 90% C.L., where we have normalized $B (Λ_{c}^{+} \to p K^{-} π^{+})$ to the world average value.
