Rare B-decays induced by flavour-changing neutral currents (FCNC) is one of the promising candidates for probing physics beyond the Standard model. However, for identifying potential new physics from the data, reliable control over QCD contributions is necessary. I focus on one of such QCD contributions - the charming loops that provide difficulties in disentangling new physics and discuss the possibility to gain control over them.
