b --> s\ell^+\ell^- in the high q^2 region at two-loops

Abstract

We report on the first analytic NNLL calculation for the matrix elements of the operators O_1 and O_2 for the inlusive process b --> X_s l^+l^- in the kinematical region q^2>4m_c^2, where q^2 is the invariant mass squared of the lepton-pair.
