Rare Non-hadronic b Decays

Abstract

This paper summarizes current results for rare non-hadronic b decay processes. The world average Br(b -> s gamma)=(3.14 +/-0.48)x10^(-4) is in agreement with the standard model prediction. Upper limits on b-> s l^+ l^- and b -> l^+ l^- are also given. Finally B^- -> l^- nu upper limits are presented as well as the world average value of (255+/- 21 +/- 28) MeV for f_{Ds} from D_s^+ -> l^+ nu decay rate measurements.
