Rare Radiative and Leptonic B Decays: Recent Results from BaBar and Belle

Recent BABAR and Belle results on rare B decays involving photons or lepton pairs are reviewed. New preliminary limits from both experiments for B {yields} {rho}{gamma} and B{sup 0} {yields} {Omega}{gamma}, and from BABAR for B{sup -} {yields} K{sup -}{nu}{bar {nu}} and B{sup +} {yields} {tau}{sup +}{nu}{sub {tau}} are presented. Also summarized from the past year are Belle measurements of B {yields} X{sub s}{ell}{sup +}{ell}{sup -} and B{sup 0} {yields} K*{sub 2}(1430){sup 0}{gamma}, preliminary BABAR measurements of B {yields} X{sub s}{gamma}, and preliminary results from BABAR and Belle on B {yields} K{sup (*)}{ell}{sup +}{ell}{sup -}. No significant deviations from Standard Model predictions have yet been found.
