英文摘要	The computation of direct CF asymmetries in charmless B decays at next-to-next-to-leading order (NNLO) in QCD is of interest to ascertain the short-distance contribution. Here we compute the two-loop penguin contractions of the current-current operators Q(1,2) and provide a first estimate of NNLO CP asymmetries in penguin-dominated b -> s transitions.
