Multiple experimental evidences show that neutrinos are massive. Among the plethora of models which explain the smallness of neutrino masses, the Seesaw mechanism stands out due to its simplicity and effectiveness. Such mechanism introduces an additional energy scale which allows for the suppression of the neutrino masses with respect to the electroweak scale. Nevertheless, the presence of an extra large energy scale induces a hierarchy problem, unless there exists a more fundamental framework. We will present a generalization of a specific case of the Seesaw mechanism, the scalar triplet scenario, which avoids the inclusion of new energy scales and the presence of arbitrarily small parameters. This model has a rich phenomenology and has a smoking gun signature at the LHC which makes possible to distinguish it from the standard scenario.
