  Viable explanations of a hinted 750 GeV scalar resonance may be sought within
the extensions of the SM Higgs sector aimed at generating neutrino masses at
the loop level. We confront a compatibility with the 750 GeV diphoton excess
for two recent models which do not need to impose ad hoc symmetry to forbid the
tree-level masses: a one-loop mass model providing the H(750) candidate within
its real triplet scalar representation and a three-loop mass model providing it
within its two Higgs doublets. Besides accounting for the 750 GeV resonance, we
demonstrate that these complementary neutrino-mass scenarios have different
testable predictions for the LHC which should show up soon as more data is
accumulated during the ongoing 13 TeV run.
