Abstract

We report a search for the decay B̄0→Λc+p̄pp̄. Using a data sample of 471×106 BB̄ 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(B̄0→Λc+p̄pp̄) ×B(Λc+→pK-π+)0.050<2.8×10-6 at 90% C.L., where we have normalized B(Λc+→pK-π+) to the world average value. © 2014 American Physical Society.
