Phys. Rev. D 83, 093008 (2011) [8 pages]Trinification, the hierarchy problem, and inverse seesaw neutrino massesReceived 20 January 2011; published 13 May 2011 In minimal trinification models light neutrino masses can be generated via a radiative seesaw mechanism, where the masses of the right-handed neutrinos originate from loops involving Higgs and fermion fields at the unification scale. This mechanism is absent in models aiming at solving or ameliorating the hierarchy problem, such as low-energy supersymmetry, since the large seesaw scale disappears. In this case, neutrino masses need to be generated via a TeV-scale mechanism. In this paper, we investigate an inverse seesaw mechanism and discuss some phenomenological consequences. © 2011 American Physical Society URL:
