摘要：

We have evaluated the short distance QCD corrections to the B-approximately --> X(s)e+e- process in a quark spectator model within an effective hamiltonian framework. The dependence of the rate on the top-quark mass is examined in the minimal standard model. We have found a light suppression of the differential width for a large invariant mass of the e+e- pair; the integrated width is slightly enhanced.
