Rare Non-hadronic b Decays
Sheldon Stone
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 fDs from Ds+ -> l+ nu decay rate measurements.
