In this note, recent results of studies of semileptonic B meson decays from
\babar\ are discussed and preliminary results given. In particular, a recent
measurement of B(B→D(∗)τν) and the ratio
B(B→D(∗)τν)/B(B→D(∗)ℓν) is
presented. For the D∗ mode, a branching fraction of
1.79\pm0.13\stat\pm0.17\syst is found, with a ratio of
0.325\pm0.023\stat\pm0.027\syst. For the D mode, the results are
1.04\pm0.12\stat\pm0.14\syst and 0.456\pm0.053\stat\pm0.056\syst,
respectively. In addition, a study of Bs production and semileptonic decays
using data collected in a center-of-mass energy region above the \Y4S resonance
is discussed. The semileptonic branching fraction B(Bs→ℓνX) is measured to be 9.9{}^{+2.6}_{-2.1}\stat{}^{+1.3}_{-2.0}\syst.Comment: 8 pages, 6 figures, Parallel talk at APS meeting of the Division of
