Popis: In this Letter we revisit the type-II seesaw mechanism based on the addition of a weak triplet scalar to the standard model. We perform a comprehensive study of its phenomenology at the LHC energies, complete with the electroweak precision constraints. We pay special attention to the doubly-charged component, object of collider searches for a long time, and show how the experimental bound on its mass depends crucially on the particle spectrum of the theory. Our study can be used as a roadmap for future complete LHC studies.
Comment: 5 pages, 4 figures; added discussion on collider signatures including the impact on SM Higgs searches and accommodating Higgs to two photon rate, and references; latest version agrees with the published one
