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 theoretical development of such ‘braneworld’ models in the late 1990s coincided with the experimental verification of nonzero neutrino masses. This presents another hierarchy problem: why are neutrino masses vanishin...
متن کاملFlavor Structure of Warped Extra Dimension Models
We recently showed, in hep-ph/0406101, that warped extra dimensional models with bulk custodial symmetry and few TeV KK masses lead to striking signals at B-factories. In this paper, using a spurion analysis, we systematically study the flavor structure of models that belong to the above class. In particular we find that the profiles of the zero modes, which are similar in all these models, ess...
متن کاملWarped Geometry in Higher Dimensions with an Orbifold Extra Dimension
We solve the Einstein equations in higher dimensions with warped geometry where an extra dimension is assumed to have orbifold symmetry, S/Z2. The setup considered here is an extension of the 5-dimensional Randall-Sundrum model to (5+D)-dimensions, and hidden and observable branes are fixed on the orbifold. It is assumed that the brane tension (self-energy) of each brane with (4+D)-dimensional ...
متن کاملHiggs decay into two photons in a warped extra dimension
A detailed five-dimensional calculation of the Higgs-boson decay into two photons is performed in both the minimal and the custodially protected Randall-Sundrum (RS) model, where the Standard Model (SM) fields propagate in the bulk and the scalar sector lives on or near the IR brane. It is explicitly shown that the [Formula: see text] gauge invariance of the sum of diagrams involving bosonic fi...
متن کاملThe Randall-Sundrum Scenario with an Extra Warped Dimension
We investigate a scenario with two four-branes embedded in six dimensions. When the metric is periodic and compact in one of the dimensions parallel to the branes, the value of the effective cosmological constant for the remaining five dimensions can assume a variety of values, determined by the dependence of the metric on the sixth dimension. The picture that emerges resembles the Randall-Sund...
