Description

We present the calculation of the virtual O(a_s) corrections to the inclusive rare decay b -> sl⁺ l^-. The new contributions drastically reduce the renormalization scale dependence of the decay spectrum. For the corresponding branching ratio the renormalization scale uncertainty gets reduced from ± 13% to ± 6.5%.
