Book excerpt: In a sample of 467 million B{bar B} pairs collected with the BABAR detector at the PEP-II collider at SLAC we have observed the decay {bar B}° →?{sub c}{bar p}?° and measured the branching fraction to be (1.94 ± 0.17 ± 0.14 ± 0.50) x 10−4, where the uncertainties are statistical, systematic, and the uncertainty on the?{sub c}+ → pK−?+ branching fraction, respectively. We determine an upper limit of 1.5 x 10−6 at 90% C.L. for the product branching fraction?({bar B}° →?{sub c}+(2455){bar p}) x?(?{sub c}+ → pK−?+). Furthermore, we observe an enhancement at the threshold of the invariant mass of the baryon-antibaryon pair.
