We report the measurement of the baryonic B decay B^\ensuremath-\ensuremath→\mathit\ensuremathΣc++p\ensuremathπ^\ensuremath-\ensuremathπ^\ensuremath-. Using a data sample of 467\ifmmode×\else\texttimes\fi106 BB pairs collected with the BABAR detector at the PEP-II storage ring at SLAC, the measured branching fraction is (2.98\ifmmode±\else\textpm\fi0.16(stat)\ifmmode±\else\textpm\fi0.15(syst)\ifmmode±\else\textpm\fi0.77_(\ensuremathΛc))\ifmmode×\else\texttimes\fi10^\ensuremath-4, where the last error is due to the uncertainty in B(\mathit\ensuremathΛc+\ensuremath→pK^\ensuremath-\ensuremathπ+). The data suggest the existence of resonant subchannels B^\ensuremath-\ensuremath→\mathit\ensuremathΛc(2595)+p\ensuremathπ^\ensuremath- and, possibly, B^\ensuremath-\ensuremath→\mathit\ensuremathΣc++\mathit\ensuremathΔ--\ensuremathπ^\ensuremath-. We see unexplained structures in m(\mathit\ensuremathΣc++\ensuremathπ^\ensuremath-\ensuremathπ^\ensuremath-) at 3.25 GeV/c2, 3.8 GeV/c2, and 4.2 GeV/c2.
