We study lepton distributions in flavor-changing neutral current induced B meson decays into a pair of light leptons along with strange states. In addition to the invariant mass distribution, we examine the polarization, forward-backward, and polarization forward-backward asymmetries of the final state leptons. The standard model predictions for these distributions are at a level which is accessible to the forthcoming B factories. We also investigate the consequence of extensions of the standard model, including models with two Higgs doublets and supersymmetric extensions. Substantial deviations in individual distributions are found in certain regions of the parameter space of specific models. Therefore confronting these findings with future measurements may either highlight new physics or place constraints on extensions beyond the standard model. We derive results determined by the structure of the effective Hamiltonian which is common to the standard model and other models, independently of the values of couplings which can vary from model to model.
