Abstract

We report a search for the decay B¯0→Λ+cp¯pp¯. Using a data sample of 471×106 BB¯ 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(B¯0→Λ+cp¯pp¯)×ℬ(Λ+c→pK−π+)0.050<2.8×10−6 at 90% C.L., where we have normalized ℬ(Λ+c→pK−π+) to the world average value.
