Despite being very successful in explaining the wide range of precisionexperimental results obtained so far, the Standard Model (SM) of elementaryparticles fails to address two of the greatest observations of the recentdecades: tiny but nonzero neutrino masses and the well-known problem of missingmass in the Universe. Typically the new models beyond the SM explain only oneof these observations. Instead, in the present article, we take the view thatthey both point towards the same new extension of the Standard Model. The newparticles introduced are responsible simultaneously for neutrino masses and forthe dark matter of the Universe. The stability of dark matter and the smallnessof neutrino masses are guaranteed by a U(1) global symmetry, broken to aremnant Z_2. The canonical seesaw mechanism is forbidden and neutrino massesemerge at the loop level being further suppressed by the small explicitbreaking of the U(1) symmetry. The new particles and interactions are invokedat the electroweak scale and lead to rich phenomenology in colliders, in leptonflavour violating rare decays and in direct and indirect dark matter searches,making the model testable in the coming future.
