Abstract. We present recent results on light mesons based on Dalitz plot analyses of charm decays from Fermilab experiment E791. Scalar mesons are found to have large contributions to the decays studied,From the Kππ final state, we find good evidence for the existence of the light and broad κ meson and we measure its mass and width. We also discuss recently published results on the 3π final states, especially the measurement of the f 0 parameters and the evidence for the σ meson from D + → σπ + . These results demonstrate the importance of charm decays as a new environment for the study of light meson physics.

“…The resolutions σ M(D) for D 0 →K − π + , K − π + π 0 , K − π + π − π + , and D + →K − π + π + are approximately 6, 10, 5, and 5 MeV/c 2 , respectively. For the modes involving D 0 →K − π + π 0 decays, the combinatoric background events due to fake π 0 candidates are suppressed using a model [36] that parameterizes the amplitude of the Dalitz plot distribution M 2 (K − π + ) vs. M 2 (π + π 0 ). The model accounts for the amplitudes and the interferences of decays of K * 0 →K − π + , K * − →K − π 0 , and ρ + →π + π 0 .…”

We present results for B-meson decay modes involving a charm meson, protons, and pions using 455×10 6 BB 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:, and B − →D * + ppπ − π − . The four B − and the two five-body B 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 (pp) and M (D ( * )0 p) invariant mass distributions show enhancements near threshold values. In the four-body mode B 0 →D + ppπ − , the M (pπ − ) distribution shows a narrow structure of unknown origin near 1.5 GeV/c 2 . The distributions for the five-body modes, in contrast to the others, are similar to the expectations from uniform phase-space predictions.
