QCD corrections to b → se e decay

We give a more complete calculation of b → se⁺ e⁻ decay including leading log QCD corrections from m_top to M_W in addition to corrections from M_W to m_b. The differential decay rate is found to be slightly suppressed for a large invariant mass of the e⁺ e⁻ pair; while the integrated width is slightly enhanced comparing with the results without the QCD running from m_top to M_W.
