Recently it was proposed that the standard model (SM) degrees of freedom reside on a (3 + 1)-dimensional wall or ''3-brane'' embedded in a higher-dimensional spacetime. Furthermore, in this picture it is possible for the fundamental Planck mass M* to be as small as the weak scale M* approximate or equal to O(TeV) and the observed weakness of gravity at long distances is due the existence of new sub-millimeter spatial dimensions. We show that in this picture it is natural to expect neutrino… Expand
Neutrinoless Double Beta Decay from Singlet Neutrinos in Extra Dimensions
We study the model-building conditions under which a sizable 0nbb-decay signal to the recently reported level of 0.4 eV is due to Kaluza-Klein singlet neutrinos in theories with large extraExpand
Neutrinos in 5D SO(10) Unification
We study neutrino physics in a 5D supersymmetric SO(10) GUT. We analyze several different choices for realizing the See-Saw mechanism. We find that the "natural" scale for the Majorana mass ofExpand
Massive Neutrinos in a Warped Extra Dimension
The Randall-Sundrum I (RS1) model of a warped extra dimension provides a natural candidate solution to the hierarchy problem between the Planck and weak scales. Coincidentally, the theoreticalExpand
Neutrinos in a warped extra dimension
Amongst the diverse propositions for extra dimensional scenarios, the model of Randall and Sundrum (RS), which offers a solution for the long standing puzzle of the gauge hierarchy problem, hasExpand
Neutrinos vis-a-vis the six-dimensional standard model
We examine the origin of neutrino masses and oscillations in the context of the six-dimensional standard model. The space-time symmetries of this model explain proton stability and forbid MajoranaExpand
Neutrino mass patterns within the seesaw model from multilocalization along extra dimensions
We study a multi-localization model for charged leptons and neutrinos, including the possibility of a see-saw mechanism. This framework offers the opportunity to allow for realistic solutions in aExpand
Dirac Vs. Majorana Neutrino Masses From a TeV Interval
Abstract We investigate the nature (Dirac vs. Majorana) and size of left-handed neutrino masses in a supersymmetric five-dimensional model compactified in the interval [ 0 , π R ] , where quarks andExpand
Neutrino masses in a 5D SU(3)W TeV unification model
Abstract We study the generation of neutrino masses in the SU(3)W electroweak unified theory in M4×S1/(Z2×Z′2) spacetime. By appropriate orbifolding, the bulk symmetry SU(3)W is broken intoExpand
Bulk fermions in multi-brane worlds
We study bulk fermion fields in various multi-brane models with localized gravity. The chiral zero mode that these models support can be identified as a right-handed sterile neutrino. In this caseExpand
Neutrino masses and mixing in brane world theories
We present a comprehensive study of five-dimensional brane-world models for neutrino physics based on flat compactifications. Particular emphasis is put on the inclusion of bulk mass terms. We deriveExpand
