Abstract
We report a search for the decay ¯ B0 → Λþc p¯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 Bð ¯ B0 → Λþc ¯pp¯pÞ × BðΛþc →pK−πþÞ 0.050 < 2.8 × 10−6 at 90% C.L., where we have normalized BðΛþc → pK−πþÞ to the world average value.
