We present measurements of branching fractions of B{sup 0} decays to multibody final states containing protons, based on 232x10{sup 6} {upsilon}(4S){yields}BB decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. We measure the branching fractions B(B{sup 0}{yields}D{sup 0}pp)=(1.13{+-}0.06{+-}0.08)x10{sup -4}, B(B{sup 0}{yields}D*{sup 0}pp)=(1.01{+-}0.10{+-}0.09)x10{sup -4}, B(B{sup 0}{yields}D{sup -}pp{pi}{sup +})=(3.38{+-}0.14{+-}0.29)x10{sup -4}, and B(B{sup 0}{yields}D*{sup -}pp{pi}{sup +})=(4.81{+-}0.22{+-}0.44)x10{sup -4} where the first error is statistical and the second systematic. We present a search for the charmed pentaquark state, {theta}{sub c}(3100) observed by H1 and put limits on the branching fraction B(B{sup 0}{yields}{theta}{sub c}p{pi}{sup +})xB({theta}{sub c}{yields}D*{sup -}p)<14x10{sup -6} and B(B{sup 0}{yields}{theta}{sub c}p{pi}{sup +})xB({theta}{sub c}{yields}D{sup -}p)<9x10{sup -6}. Upon investigation of the decay structure of the above four B{sup 0} decay modes, we see an enhancement at low pp mass and deviations from phase-space in the Dp and Dp invariant mass spectra.
