Abstract

In this review, the most recent results of the radiative decays B -> X_s gamma, B -> K^{(*)} l^+ l^-$ and B -> pi/eta l^+ l^- at e^+e^- colliders are discussed. The new, most precise CP asymmetry measurements in B -> X_s gamma from BABAR are presented together with branching fractions and photon energy moments. For B -> K^{(*)} l^+ l^- modes, B factory results on partial branching fractions, rate asymmetries and angular observables are combined with measurements from CDF and the LHC experiments. The first branching fraction upper limits for B -> eta l^+ l^- are shown along with updated upper limits of B -> pi l^+ l^- branching fractions.
