In the latter scenario the singly and doubly charged scalars that are new in the Zee-Babu model can explain the large annihilation cross section of a dark matter pair into two photons as hinted by the recent analysis of the Fermi $\\gamma$-ray space telescope data. These new scalars can also enhance the $B ( H \\rightarrow \\gamma\\gamma )$, as the recent LHC results may suggest.
