Abstract
We present a search for the rare, flavour-changing-neutral-current decay $B^- \to \Lambda {\overline p} \nu{\overline{\nu}}$ at the BaBar experiment. We see no evidence for signal decays and set an upper limit of ${\cal B}(B^- \to \Lambda {\overline p} \nu{\overline{\nu}})<3.0\times10^{-5}$ at the 90% confidence level. This result is the first experimental limit on this decay mode.
