摘要：

We recalculate the rate asymmetries in rare B-decays on the quark level to order alpha-s2, taking into account all gg intermediate states. In contrast to previous investigations, we find the total asymmetries to lie below 1%, except for b --> d + (ddBAR, ssBAR) where it is 4%. The asymmetry of differential rates reaches 3% in b --> suuBAR for large momentum transfer. The complete calculation is outlined and the infrared problems are analyzed. We comment on the decay B(s) --> gg.
