Echoes from a Warped Dimension
The Randall-Sundrum (RS) model, based on a slice of warped 5D spacetime, was originally introduced to explain the apparent hierarchy between the scales of weak and gravitational interactions. Over the past decade, this model has been extended to provide a predictive theory of flavor, as well as to address various constraints from precision data. In this talk, we will present a brief review of t...
متن کاملA Model of Lepton Masses from a Warped Extra Dimension
In order to explain the non-hierarchical neutrino mixing angles and the absence of lepton flavor violating processes in the context of warped extra dimensions one needs to introduce bulk flavor symmetries. We present a simple model of lepton masses and mixings in RS models based on the A4 non-abelian discrete symmetry. The virtues of this choice are: (i) the natural appearance of the tri-bimaxi...
متن کاملMassive 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 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...
