• We emphasize , however , that the structure of the mixing matrix V Hd can differ significantly from the known structure of the CKM matrix so that interesting departures from MFV correlations between various processes are possible . Basically all MFV correlations between K , B 0 d and B 0 s meson systems can be modified , while being still consistent with the existing data , even if these modifications amount to at most 30 % in the case of the CP - conserving observables considered here .
