Resumen:
A new realization for radiative neutrino mass generation is presented.
Based on the requirement of tree-level custodial symmetry and the
introduction of higher (greater than two) dimensional representations
for scalar fields, a specific scenario with a scalar septet is presented
that generates neutrino Majorana masses radiatively. This is
accomplished through an eleven dimensional operator that requires the
addition of several scalar fields and a SU(2) 5-plet of new fermions,
together with a Z(2) that guarantees the preservation of custodial
symmetry. The phenomenology of the setup is rather rich and includes a
dark matter candidate. (C) 2016 The Authors. Published by Elsevier B.V.
