dc.description.abstract | We report the measurement of the baryonic B decay B − → Σ ++ c ¯ p π − π − . Using a data sample of 467 × 10 6 B ¯¯¯ B pairs collected with the BABAR detector at the PEP-II storage ring at SLAC, the measured branching fraction is ( 2.98 ± 0.16 ( stat ) ± 0.15 ( syst ) ± 0.77 ( Λ c ) ) × 10 − 4 , where the last error is due to the uncertainty in B ( Λ + c → p K − π + ) . The data suggest the existence of resonant subchannels B − → Λ c ( 2595 ) + ¯ p π − and, possibly, B − → Σ ++ c ¯¯¯ Δ −− π − . We see unexplained structures in m ( Σ ++ c π − π − ) at 3.25 GeV / c 2 , 3.8 GeV / c 2 , and 4.2 GeV / c 2 . | - |
