New tools for fermion masses from extra dimensions

  title={New tools for fermion masses from extra dimensions},

We present models in which the observed fermion masses and mixings are generated by dynamically localizing the three generations of matter in a flat compact extra dimension. We first construct models assuming the hierarchy problem is addressed by the existence of large extra dimensions, i.e. the fundamental scale is not far above a TeV and supersymmetry is not imposed. These models are compactified, chiral, and don't require fine-tuning to generate the top mass. Limits on the compactification… Expand

Fermion Generations, Masses and Mixing Angles from Extra Dimensions
Abstract We discuss a toy model in six dimensions that predicts two fermion generations, natural mass hierarchy and intergenerational mixing. Matter is described by vector-like six-dimensionalExpand
Collider phenomenology of extra dimensions
In recent years there has been much interest in the possibility that there exist more spacetime dimensions than the usual four. Models of particle physics beyond the Standard Model that incorporateExpand
Flavorful Supersymmetry from Higher Dimensions
We present models of flavorful supersymmetry in higher dimensions. The Higgs fields and the supersymmetry breaking field are localized in the same place in the extra dimension(s). The YukawaExpand
Yukawa hierarchies from extra dimensions with small FCNC
We investigate a class of extra dimensional models where all of the Standard Model fermions are localized to a single fixed point in an S{sub 1}/Z{sub 2} orbifold, and each species is localized withExpand
CKM pattern from localized generations in extra dimension
We revisit the issue of the quark masses and mixing angles in the framework of large extra dimension. We consider three identical standard model families resulting from higher-dimensional fieldsExpand
A simple model of generating fermion mass hierarchy in N=1 supersymmetric 6D SO(10) GUT
Abstract We suggest a simple model which produces the suitable fermion mass hierarchies and flavor mixing angles based on the 6-dimensional N =1 supersymmetric SO (10) grand unified theoryExpand
'Dynamical Supersymmetry Breaking, with Flavor'
We explore calculable models with low-energy supersymmetry where the flavor hierarchy is generated by quark and lepton compositeness, and where the composites emerge from the same sector thatExpand
A realistic pattern of fermion masses from a five-dimensional SO(10) model
A bstractWe provide a unified description of fermion masses and mixing angles in the framework of a supersymmetric grand unified SO(10) model with anarchic Yukawa couplings of order unity. TheExpand
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
Inverted sparticle hierarchies from natural particle hierarchies
A possible resolution of the flavor puzzle is that the fermion mass hierarchy can be dynamically generated through the coupling of the first-two-generation fields to a strongly coupled sector, whichExpand


A Warped supersymmetric standard model
Abstract We study the breaking of supersymmetry in five-dimensional (5d) warped spaces, using the Randall–Sundrum model as a prototype. In particular, we present a supersymmetry-breaking mechanismExpand
Softly Broken Supersymmetric Desert from Orbifold Compactification
A new viewpoint for the gauge hierarchy problem is proposed: compactification at a large scale, 1/R, leads to a low energy effective theory with supersymmetry softly broken at a much lower scale,Expand
Neutrino masses with a single generation in the bulk
In a class of multidimensional models, topology of the thick brane provides three chiral fermionic families with hierarchical masses and mixings in the effective four-dimensional theory, while theExpand
SO(10) unified theories in six-dimensions
We construct supersymmetric models of SO(10) unification in which the gauge symmetry is broken by orbifold compactification. We find that using boundary conditions to break the gauge symmetry down toExpand
