NNLL QCD Corrections to the Decay $B \to X_s \ell^+ \ell^-$
We briefly discuss the status of the NNLL QCD calculations in the inclusive rare $B$ decay $B \rightarrow X_s \ell^+ \ell^-$. Two important ingredients, the two-loop matrix elements of the four quark operator ${\cal O}_2$ and the bremsstrahlung contributions, were quite recently finalised. The new c...
