We present results for B-meson decay modes involving a charm meson, protons, and pions using 455×106 BB̅ pairs recorded by the BaBar detector at the SLAC PEP-II asymmetric-energy e+e- collider. The branching fractions are measured for the following ten decays: B̅ 0→D0pp̅ , B̅ 0→D*0pp̅ , B̅ 0→D+pp̅ π-, B̅ 0→D*+pp̅ π-, B-→D0pp̅ π-, B-→D*0pp̅ π-, B̅ 0→D0pp̅ π-π+, B̅ 0→D*0pp̅ π-π+, B-→D+pp̅ π-π-, and B-→D*+pp̅ π-π-. The four B- and the two five-body B̅ 0 modes are observed for the first time. The four-body modes are enhanced compared to the three- and the five-body modes. In the three-body modes, the M(pp̅ ) and M(D(*)0p) invariant-mass distributions show enhancements near threshold values. In the four-body mode B̅ 0→D+pp̅ π-, the M(pπ-) distribution shows a narrow structure of unknown origin near 1.5 GeV/c2. The distributions for the five-body modes, in contrast to the others, are similar to the expectations from uniform phase-space predictions.

Abstract

We present results for B-meson decay modes involving a charm meson, protons, and pions using 455×106 BB̅ pairs recorded by the BaBar detector at the SLAC PEP-II asymmetric-energy e+e- collider. The branching fractions are measured for the following ten decays: B̅ 0→D0pp̅ , B̅ 0→D*0pp̅ , B̅ 0→D+pp̅ π-, B̅ 0→D*+pp̅ π-, B-→D0pp̅ π-, B-→D*0pp̅ π-, B̅ 0→D0pp̅ π-π+, B̅ 0→D*0pp̅ π-π+, B-→D+pp̅ π-π-, and B-→D*+pp̅ π-π-. The four B- and the two five-body B̅ 0 modes are observed for the first time. The four-body modes are enhanced compared to the three- and the five-body modes. In the three-body modes, the M(pp̅ ) and M(D(*)0p) invariant-mass distributions show enhancements near threshold values. In the four-body mode B̅ 0→D+pp̅ π-, the M(pπ-) distribution shows a narrow structure of unknown origin near 1.5 GeV/c2. The distributions for the five-body modes, in contrast to the others, are similar to the expectations from uniform phase-space predictions.
