Sumario: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. Topological vertex criteria are used to separate the B -> D**+ l nu X signal from background as well as to search for the non-resonant component B -> D0 pi l nu X. Preliminary results for the branching fraction into resonant and non-resonant components are presented.
