Theories where the Standard Model fields reside on a 3-brane, with a low fundamental cut-off and extra dimensions, provide alternative solutions to the gauge hierarchy problem. However, generating flavor at the TeV scale while avoiding flavor-changing difficulties appears prohibitively difficult at first sight. We argue to the contrary that this picture allows us to lower flavor physics close to the TeV scale. Small Yukawa couplings are generated by ``shining'' badly broken flavor symmetries… Expand

Flavor alignment via shining in Randall-Sundrum models
We present a class of warped extra dimensional models whose flavor violating interactions are much suppressed compared to the usual anarchic case due to flavor alignment. Such suppression can beExpand
Lepton masses and mixing in a left-right symmetric model with a TeV scale gravity
We construct a left-right symmetric (LRS) model in five dimensions which accounts naturally for the lepton flavor parameters. The fifth dimension is described by an orbifold, S_1/Z_2 times Z'_2, withExpand
Flavor Symmetries in Extra Dimensions
We present a class of models of flavor that rely on the use of flavor symmetries and the Froggart-Nielsen mechanism in extra dimensions. The particle content is that of the standard model plus anExpand
Natural Neutrino Masses and Mixings from Warped Geometry
We demonstrate that flavor symmetries in warped geometry can provide a natural explanation for large mixing angles and economically explain the distinction between the quark and lepton flavorExpand
Fermion Masses and Mixing in Four and More Dimensions
We give an overview of recent progress in the study of fermion mass and flavor mixing phenomena. Mass matrix ansatze are considered within the Standard Model (SM) and SUSY GUT's where some predictiveExpand
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
Low scale flavor gauge symmetries
We study the possibility of gauging the Standard Model flavor group. Anomaly cancellation leads to the addition of fermions whose mass is inversely proportional to the known fermion masses. In thisExpand
A rationale for long-lived quarks and leptons at the LHC: low energy flavour theory
A bstractIn the framework of gauged flavour symmetries, new fermions in parity symmetric representations of the standard model are generically needed for the compensation of mixed anomalies. The keyExpand
Shining flavor and radion phenomenology in warped extra dimension
We study radion phenomenology in the context of flavor shining in warped extra dimension models. In this unique setup, originally proposed by Rattazzi and Zaffaroni, solutions to the gauge hierarchyExpand
Finite radiative electroweak symmetry breaking from the bulk
Abstract A new physical origin for electroweak symmetry breaking is proposed, involving compact spatial dimensions of scale 1/ R ≈1 TeV. The higher-dimensional theory is supersymmetric, and henceExpand
