ResumenWe present a measurement of the B-0 -> (Lambda) over barp pi(-) branching fraction performed using the BABAR detector at the PEP-II asymmetric e(+)e(-) collider. Based on a sample of 467 x 10(6) B (B) over bar pairs we measure B(B-0 -> (Lambda) over barp pi(-)) = [3.07 +/- 0.31(stat) +/- 0.23(syst)] x 10(-6). The measured differential spectrum as a function of the dibaryon invariant mass m((Lambda) over barp) shows a near-threshold enhancement similar to that observed in other baryonic B decays. We study the (Lambda) over bar polarization as a function of (Lambda) over bar energy in the B-0 rest frame (E-(Lambda) over bar*) and compare it with theoretical expectations of fully longitudinally right-polarized (Lambda) over bar at large E-(Lambda) over bar*.
