The authors present measurements of branching fractions of B{sup 0} decays to multi-body final states containing protons, based on 232 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. They measure the branching fractions {Beta}(B{sup 0} {yields} {bar D}{sup 0} p{bar p}) = (1.13 {+-} 0.06 {+-} 0.08) x 10{sup -4} {Beta}(B{sup 0} {yields} {bar D}*{sup 0} p{bar p}) = (1.01 {+-} 0.10 {+-} 0.09) x 10{sup -4}, {Beta}(B{sup 0} {yields} D{sup -} p{bar p}{pi}{sup +}) = (3.38 {+-} 0.14 {+-} 0.29) x 10{sup -4}, and {Beta}(B{sup 0} {yields} D*{sup -} p{bar p}{pi}{sup +}) = (4.81 {+-} 0.22 {+-} 0.44) x 10{sup -4} where the first error is statistical and the second systematic. They present a search for the charmed pentaquark state, {Theta}{sub c}(3100) observed by H1 and put limits on the branching fraction {Beta}(B{sup 0} {yields} {Theta}{sub c}{bar p}{pi}{sup +}) x {Beta}({Theta}{sub c} {yields} D*{sup -}p) < 14 x 10{sup -6} and {Beta}(B{sup 0} {yields} {Theta}{sub c}{bar p}{pi}{sup +}) x {Beta}({Theta}{sub c} {yields} D{sup -}p) < 9 x 10{sup -6}. Upon investigation of the decay structure of the above four B{sup 0} decay modes, they see an enhancement at low p{bar p} mass and deviations from phase-space in the {bar D}{bar p} and {bar D}p invariant mass spectra.
