Results from BABAR's full dataset are presented for the angular analysis of the rare decay B -> K*l+l-, where l represents an electron or muon, including measurements of the longitudinal K* polarization and the lepton forward-backward asymmetry.
BABAR results are presented for B -> Xs gamma decays, including branching fraction and photon spectrum measurements from both a fully inclusive analysis and a semi-inclusive analysis that reconstructs 38 distinct final states for Xs.
ORKA is an experiment to observe of order 1000 K+ -> pi+ nu nubar events and to make a precision measurement of the branching fraction. It has been proposed to run at Fermilab using the Main Injector. This note describes ORKA and its current status.
We review recent results from the BABAR and Belle experiments on rare electroweak B-meson decays, with emphasis on those occurring through flavor changing neutral current interactions of the type b -> s l l. The recent results include measurements of the isospin asymmetry and lepton forward-backward asymmetry in B -> K* l+ l- decays from BABAR, a search for B -> pi l+ l- from Belle, and searches for B \to K(*) nu anti-nu from BABAR. We also briefly review the status of B0 -> l+ l- and B+ -> l+ nu searches.
