ResumoWe compute the inclusive rate for a B-meson to decay to strange hadronic final states and a large mass electron-positron pair: B→Xse+e−. The dependence of the rate on the invariant mass of the e+e− pair is examined. The computation is done in the standard six-quark model with a minimal Higgs sector and in extensions of the standard model with two Higgs doublets. For e+e− pairs with very large invariant mass the strange hadronic final states Xs must have low mass. In this kinematic region we estimate the rate for B→Ke+e− using the nonrelativistic quark model.
