Large Extra Dimensions from a Small Extra Dimension [PDF]

, 2001
Models with extra dimensions have changed our understanding of the hierarchy problem. In general, these models explain the weakness of gravity by diluting gravity in a large bulk volume, or by localizing the graviton away from the standard model. In this

Interpreting the 3 TeV WH resonance as a W′ boson

Journal of High Energy Physics, 2017
Motivated by a local 3.2 − 3.4 sigma resonance in WH and ZH in the ATLAS Run 2 data, we attempt to interpret the excess in terms of a W′ boson in a SU(2)1 × SU(2)2×U(1)X model. We stretch the deviation from the alignment limit of the Equivalence Theorem,

Aspects of Axion Phenomenology in a slice of AdS_5 [PDF]

, 2006
Motivated by multi-throat considerations, we study the phenomenological implications of a bulk axion in a slice of AdS_5 with a large extra dimension: k~0.01 eV, kR > 1.

Grand Unification at Intermediate Mass Scales through Extra Dimensions [PDF]

, 1998
One of the drawbacks of conventional grand unification scenarios has been that the unification scale is too high to permit direct exploration. In this paper, we show that the unification scale can be significantly lowered (perhaps even to the TeV scale ...

Exact greybody factors for the brane scalar field of five-dimensional rotating black holes

Journal of High Energy Physics, 2019
We study scalar perturbations of the five-dimensional rotating black holes and find an exact solution giving exact description of the Hawking radiation.

Phenomenology of the Neutrino-Mass-Giving Higgs Triplet and the Low-Energy Seesaw Violation of Lepton Number [PDF]

, 2000
Small realistic Majorana neutrino masses can be generated via a Higgs triplet $(\xi^{++}, \xi^+, \xi^0)$ without having energy scales larger than $M_*={\cal O}(1)$ TeV in the theory.

R D * $$ {R}_{D^{\left(*\right)}} $$ in custodial warped space

Journal of High Energy Physics, 2018
Flavor physics experiments allow to probe the accuracy of the Standard Model (SM) description at low energies, and are sensitive to new heavy gauge bosons that couple to quarks and leptons in a relevant way.

A Large Mass Hierarchy from a Small Extra Dimension [PDF]

, 1999
We propose a new higher-dimensional mechanism for solving the Hierarchy Problem. The Weak scale is generated from a large scale of order the Planck scale through an exponential hierarchy.

Bounds on Bosonic Topcolor [PDF]

, 2000
We consider the phenomenology of models in which electroweak symmetry breaking is triggered by new strong dynamics affecting the third generation and is transmitted to the light fermions via a fundamental Higgs doublet. While similar in spirit to the old

Electroweak Kaluza-Klein dark matter

Journal of High Energy Physics, 2017
In models with universal extra dimensions (UED), the lightest Kaluza-Klein excitation of neutral electroweak gauge bosons is a stable, weakly interacting massive particle and thus is a candidate for dark matter thanks to Kaluza-Klein parity.
