Infinitely Large New Dimensions [PDF]

, 1999
We construct intersecting brane configurations in Anti-de-Sitter space localizing gravity to the intersection region, with any number $n$ of extra dimensions.

Constraining compressed versions of MUED and MSSM using soft tracks at the LHC

Journal of High Energy Physics, 2017
A compressed spectrum is an anticipated hideout for many beyond standard model scenarios. Such a spectrum naturally arises in the minimal universal extra dimension framework and also in supersymmetric scenarios.

Analytical Green’s functions for continuum spectra

Journal of High Energy Physics, 2021
Green’s functions with continuum spectra are a way of avoiding the strong bounds on new physics from the absence of new narrow resonances in experimental data.

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.

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,

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

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 ...

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.

A small weak scale from a small cosmological constant

Journal of High Energy Physics, 2017
We propose a framework in which Weinberg’s anthropic explanation of the cosmological constant problem also solves the hierarchy problem. The weak scale is selected by chiral dynamics that controls the stabilization of an extra dimension.

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.
