Generation of Small Neutrino Majorana Masses in a Randall-Sundrum Model
We propose a model, in the framework of 5D with warped geometry, in which small neutrino Majorana masses are generated by tree level coupling of lepton doublets to a SU(2)L-triplet scalar field, which is coupled to a bulk SM-singlet. The neutrino mass scale is determined by the bulk mass term (αS) of the singlet as veS. This suppression is due to a small overlap between the profile of the singl...
متن کاملRealistic Neutrino Masses from Multi-Brane Extensions of the Randall-Sundrum Model ?
Scenarios based on the existence of large or warped (Randall-Sundrum model) extra dimensions have been proposed for addressing the long standing puzzle of gauge hierarchy problem. Within the contexts of both those scenarios, a novel and original type of mechanism generating small (Dirac) neutrino masses, which relies on the presence of additional right-handed neutrinos that propagate in the bul...
متن کاملRadiative Majorana Neutrino Masses
We present new radiative mechanisms for generating Majorana neutrino masses, within an extension of the standard model that successfully generates radiative charged lepton masses, order by order, from heavy sequential leptons. Only the new sequential neutral lepton has a right-handed partner, and its Majorana mass provides the seed for Majorana neutrino mass generation. Saturating the cosmolog-...
متن کاملSmall Cosmological Constants from a Modified Randall-Sundrum Model
We study a mechanism, inspired from the mechanism for generating the gauge hierarchy in RandallSundrum model, to investigate the cosmological constant problem. First we analyze the bulk cosmological constant and brane vacuum energies in RS model. We show that the five-dimensional bulk cosmological constant and the vacuum energies of the two branes all obtain their natural values. Finally we arg...
متن کاملSupersymmetric Model of Radiative Seesaw Majorana Neutrino Masses
The radiative seesaw mechanism proposed recently is minimally extended to include supersymmetry in a specific model. Relevant related issues such as leptogenesis and dark matter are discussed. If the standard model (SM) of particle interactions is extended to include three heavy neutral singlet Majorana fermions Ni (i = 1, 2, 3) and a second scalar doublet η = (η , η) with zero vacuum expectati...
