Query: Type II Seesaw Higgsology and LEP/LHC constraints   In the {\sl type II seesaw} model, if spontaneous violation of the lepton
number conservation prevails over that of explicit violation, a rich Higgs
sector phenomenology is expected to arise with light scalar states having mixed
charged-fermiophobic/neutrinophilic properties. We study the constraints on
these light CP-even ($h^0$) and CP-odd ($A^0$) states from LEP exclusion
limits, combined with the so far established limits and properties of the
$125-126$~GeV ${\cal H}$ boson discovered at the LHC. We show that, apart from
a fine-tuned region of the parameter space, masses in the $\sim 44$ to $80$ GeV
range escape from the LEP limits if the vacuum expectation value of the Higgs
triplet is $\lesssim {\cal O}(10^{-3})$GeV, that is comfortably in the region
for 'natural' generation of Majorana neutrino masses within this model. In the
lower part of the scalar mass spectrum the decay channels ${\cal H} \to h^0
h^0, A^0 A^0$ lead predominantly to heavy flavor plus missing energy or to
totally invisible Higgs decays, mimicking dark matter signatures without a dark
matter candidate. Exclusion limits at the percent level of these
(semi-)invisible decay channels would be needed, together with stringent bounds
on the (doubly-)charged states, to constrain significantly this scenario. We
also revisit complementary constraints from ${\cal H} \to \gamma \gamma$ and
${\cal H} \to Z \gamma$ channels on the (doubly)charged scalar sector of the
model, pinpointing non-sensitivity regions, and carry out a likeliness study
for the theoretically allowed couplings in the scalar potential.
