“…The validity of the OPE and the renormalization-group-improved perturbation theory in the charm contribution to the charged mode has been critically analysed: the separate scale dependence within the charm contribution of 13% at NLL QCD is consistent with partial NNLL results [195]. Moreover, subleading power corrections within the OPE of order m 2 K /m 2 c -which might lead to 15% correction -are estimated to be at the level of 5%.…”

We give a status report on inclusive rare B decays, highlighting recent developments and open problems. We focus on the decay modes B → X s,d γ, B → X s ℓ + ℓ − and B → X s νν and on their role in the search for new physics.Most of the inclusive rare B decays are important modes of flavour physics due to the small hadronic uncertainties. They can be regarded as laboratories to search for new physics.We collect the experimental data already available from CLEO and the B factories BABAR and BELLE. We review the NLL and NNLL QCD calculations of the inclusive decay rates that were recently completed, and discuss future prospects, especially the issue of the charm mass scheme ambiguity. Finally, we analyse the phenomenological impact of these decay modes, in particular on the CKM phenomenology and on the indirect search for supersymmetry.We also briefly discuss direct CP violation in inclusive rare B decays, as well as the rare kaon decays K + → π + νν and K L → π 0 νν, which offer complementary theoretically clean information.
