Selected ARGUS results on B meson decays

Semileptonic B meson decays have been studied using the ARGUS detector at DORIS II. The branching ratio for the decay bar B0→D*+l-bar ν has been measured. A significant rate for the decay bar B→D**l-bar ν has been observed. From an angular analysis of the cascade bar B0→D*+(→D0π+)l+bar ν, the forward-backward asymmetry AFB and the D*+ polarization parameter α have been determined. The decay bar B0→D*+l-bar ν have been also measured with partial reconstruction of the D*+ meson, and for the first time the inclusive primary electron spectrum in the whole momentum interval has been analyzed
