Inverse see-saw from higher than d=5 effective operatos in SUSY, and its phenomenological implications at the LHC — •Martin Bernhard Krauss¹, Toshihiko Ota², Werner Porod¹, and Walter Winter¹ — ¹Institut für Theoretische Physik und Astrophysik, Universität Würzburg, Am Hubland, 97074 Würzburg, Germany — ²Max-Planck-Institut für Physik (Werner-Heisenberg-Institut), Föhringer Ring 6, 80805 München, Germany

We discuss neutrino masses generated by higher than d=5 effective operators in a supersymmetric framework. We illustrate that at tree level, many possibilities lead to inverse see-saw scenarios with the lepton number violating term naturally suppressed by a heavy mediator mass. We show one example with heavy fermion doublets as additional mediators. This scenario may have LHC-observable phenomenology, since the added fermions lead to lepton number violating processes with displaced vertices.
