Radiative corrections for several heavy fermions bound together via the Higgs boson exchange are studied. The fermion bags considered include 12, or fewer, fermions occupying the lowest S1/2 shell. It is shown that for “moderately heavy” fermions with masses 0.4⩽mc2⩽1 TeV the radiative corrections are small, ∼10− 2, and have an attractive nature. Therefore, they do not put existence of the fermion bag in doubt. This proves that these fermion bags can exist in Nature.
