    “…A Study of Charged P-wave D Meson Production in Semileptonic B Decays. A search for the semileptonic decay of B mesons into final states involving charged D** as well as non resonant D0-pi is performed in a sample of approximately 3 million hadronic Z decays recorded with the ALEPH detector at LEP. …”

    “…A simple model of isospin and charge symmetry breaking due to external$pi^0-eta$ meson mixing is presented. It is based on amplitudes extracted from the available experimental data for pd$rightarrow^3$He$pi^0$, pd$rightarrow^3$He$eta$ and dd$rightarrow^4$He$eta$ reactions. …”

    “…We point out the relevance, in both cases, of non resonant amplitudes, where the \pi^+ \pi^- pair is produced by weak decay of a B^* (J^P=1^-) or B_0 (J^P=0^+) off-shell meson. In particular, for the B decay channel, the inclusion of the B_0 pole completes some previous analyses and confirms their conclusions, provided a suitable cut in the Dalitz plot is performed; for the B_s decay the inclusion of the B^*, B_0 amplitudes enhances the role of the tree diagrams as compared to penguin amplitudes, which makes the theoretical uncertainty related to the B_s => rho^0 K_S decay process less significant. …”
