  The recent observation of a Higgs boson at the LHC and experimental
confirmation of nonvanishing neutrino-mixing parameter sin(theta_13) offer
important means to test physics beyond the standard model. We explore this
within the context of the scotogenic model, in which neutrinos acquire mass
radiatively via one-loop interactions with dark matter. Starting with a
two-parameter neutrino-mixing matrix which is consistent with the latest
neutrino-oscillation data at the one-sigma level, we derive different sets of
solutions for the Yukawa couplings of the nonstandard particles in the model
and use the results to consider the Higgs decays into final states involving
the new particles. Assuming that the lightest one of them serves as fermionic
cold dark matter, we show that such decays are allowed by various experimental
and theoretical constraints to have substantial rates that are already
restricted by the current LHC data. We also look at their correlations with the
Higgs decays into gamma gamma and gamma Z. Upcoming LHC measurements of the
Higgs boson can therefore either detect scotogenic signals or place further
constraints on the model.
