We explore, within the warped extra dimensional framework, the possibility of finding antimatter signals in cosmic rays (CRs) from dark matter (DM) annihilation. We find that exchange of order 100 GeV radion, an integral part of this class of models, generically results in a sizable Sommerfeld enhancement of the annihilation rate for DM mass at the TeV scale. No ad hoc dark sector is required to obtain boosted annihilation cross sections and hence signals. Such a mild hierarchy between the… 
Warped radion dark matter
Warped scenarios offer an appealing solution to the hierarchy problem. We consider a non-trivial deformation of the basic Randall-Sundrum framework that has a KK-parity symmetry. This leads to a
A warped model of dark matter
We present a model of dark matter in a warped extra dimension in which the dark sector mass scales are naturally generated without supersymmetry. The dark force, responsible for dark matter
WIMP dark matter through the dilaton portal
A bstractWe study a model in which dark matter couples to the Standard Model through a dilaton of a sector with spontaneously broken approximate scale invariance. Scale invariance fixes the dilaton
Z-portal dark matter
We propose to generalize the extensions of the Standard Model where the Z boson serves as a mediator between the Standard Model sector and the dark sector χ. We show that, like in the Higgs portal
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 hierarchy
Gravity-mediated (or composite) dark matter
Dark matter could have an electroweak origin, yet it could communicate with the visible sector exclusively through gravitational interactions. In a setup addressing the hierarchy problem, we propose
Neutrino masses from an A4 symmetry in holographic composite Higgs models
We show that holographic composite Higgs Models with a discrete A4 symmetry can be built, which naturally predict hierarchical charged lepton masses and an approximate tri-bimaximal lepton mixing
Ultravisible warped model from flavor triviality and improved naturalness
A warped extra-dimensional model, where the standard model Yukawa hierarchy is set by UV physics, is shown to have a sweet spot of parameters with improved experimental visibility and possibly
Interactions of a Stabilized Radion and Duality
We determine the couplings of the graviscalar radion in Randall-Sundrum models to Standard Model fields propagating in the bulk of the space, taking into account effects arising from the dynamics of


Baryon number in warped grand unified theories: model building and (dark matter related) phenomenology
In the past year, a new non-supersymmetric framework for electroweak symmetry breaking (with or without Higgs) involving SU(2)L × SU(2)R × U(1)B−L in higher dimensional warped geometry has been
A theory of dark matter
� > 1GeV 1 . The long range allows a Sommerfeld enhancement to boost the annihilation cross section as required, without altering the weak-scale annihilation cross section during dark matter
Prospects for indirect detection of neutralino dark matter
Dark matter candidates arising in models of particle physics incorporating weak scale supersymmetry may produce detectable signals through their annihilation into neutrinos, photons, or positrons. A
Warped unification, proton stability, and dark matter.
We show that solving the problem of baryon-number violation in nonsupersymmetric grand unified theories (GUT's) in warped higher-dimensional spacetime can lead to a stable Kaluza-Klein particle. This
Radion phenomenology in realistic warped space models
We investigate the phenomenology of the Randall-Sundrum (RS) radion in realistic models of electroweak symmetry breaking with bulk gauge and fermion fields, since the radion may turn out to be the
B-factory signals for a warped extra dimension.
Study of predictions for B physics in a class of warped extra dimension models recently introduced, where few TeV Kaluza-Klein masses are consistent with electroweak data due to custodial symmetry finds clean extractions of unitarity angles are likely to be affected.
Breit-Wigner Enhancement of Dark Matter Annihilation
Dark matter of the universe has been discussed since 1933, yet its nature still remains elusive[1]. Seventy-five years later we only managed to restrict its mass between 10 31 and 10 50 GeV,
A 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
