Multi-field inflation and the field-space metric
Joshua Erlich, Jackson Olsen, Zhen Wang
Multi-field inflation models include a variety of scenarios for how inflation proceeds and ends. Models with the same potential but different kinetic terms are common in the litera…
Dante's Waterfall
Christopher D. Carone, Joshua Erlich, Anuraag Sensharma +1
We describe a hybrid axion-monodromy inflation model motivated by the Dante's Inferno scenario. In Dante's Inferno, a two-field potential features a stable trench along which a lin…
An Introduction to Holographic QCD for Nonspecialists
Joshua Erlich
Holographic QCD is an extra-dimensional approach to modeling hadrons, the bound states of the strong interactions. In holographic models, the extra spatial dimension creates a wave…
Light-Front Holographic QCD and Emerging Confinement
Stanley J. Brodsky, Guy F. de Teramond, Hans Gunter Dosch +1
In this report we explore the remarkable connections between light-front dynamics, its holographic mapping to gravity in a higher-dimensional anti-de Sitter (AdS) space, and confor…
A Permutation on Hybrid Natural Inflation
Christopher D. Carone, Joshua Erlich, Marc Sher +1
We analyze a model of hybrid natural inflation based on the smallest non-Abelian discrete group S_3. Leading invariant terms in the scalar potential have an accidental global symme…
Model Sensitivity in Holographic Superconductors and their Deconstructed Cousins
Joshua Erlich, Zhen Wang
Holographic models of superconductors successfully reproduce certain experimental features of high-temperature superconductors, such as a large gap-to-T_c ratio compared to that of…
Nonlinear Boundary Dynamics and Chiral Symmetry in Holographic QCD
Dylan Albrecht, Joshua Erlich, Ronald J. Wilcox
In a hard-wall model of holographic QCD, we find that nonlinear boundary dynamics are required in order to maintain the correct pattern of explicit and spontaneous chiral symmetry…
Decaying Dark Matter from Dark Instantons
Christopher D. Carone, Joshua Erlich, Reinard Primulando
We construct an explicit, TeV-scale model of decaying dark matter in which the approximate stability of the dark matter candidate is a consequence of a global symmetry that is brok…
Pion condensation in holographic QCD
Dylan Albrecht, Joshua Erlich
We study pion condensation at zero temperature in a hard-wall holographic model of hadrons with isospin chemical potential. We find that the transition from the hadronic phase to t…
How Well Does AdS/QCD Describe QCD?
Joshua Erlich
AdS/QCD is an extra-dimensional approach to modeling hadronic physics, motivated by the AdS/CFT correspondence in string theory. AdS/QCD models are often more accurate than would h…
Recent Results in AdS/QCD
Joshua Erlich
AdS/QCD is an extra-dimensional approach to modeling the light hadronic resonances in QCD. AdS/QCD models are generally successful at reproducing low-energy observables with around…
Tests of Universality in AdS/QCD
Joshua Erlich, Christopher Westenberger
Estimates of the light hadron masses, decay constants and couplings in AdS/QCD models are generally more accurate than should have been expected. Certain predictions based on the A…
Extra Gauge Invariance from an Extra Dimension
Christopher D. Carone, Joshua Erlich, Marc Sher
We describe higher-dimensional theories whose low-energy 4D descriptions contain larger gauge or global symmetry groups. As an example, we construct a Higgsless SU(2) x U(1) model…
Sensitivity and Insensitivity of Galaxy Cluster Surveys to New Physics
Joshua Erlich, Brian Glover, Neal Weiner
We study the implications and limitations of galaxy cluster surveys for constraining models of particle physics and gravity beyond the Standard Model. Flux limited cluster counts p…
Holographic Bosonic Technicolor
Christopher D. Carone, Joshua Erlich, Jong Anly Tan
We consider a technicolor model in which the expectation value of an additional, possibly composite, scalar field is responsible for the generation of fermion masses. We define the…
Dynamically Warped Theory Space and Collective Supersymmetry Breaking
Christopher D. Carone, Joshua Erlich, Brian Glover
We study deconstructed gauge theories in which a warp factor emerges dynamically and naturally. We present nonsupersymmetric models in which the potential for the link fields has t…
QCD and a Holographic Model of Hadrons
Joshua Erlich, Emanuel Katz, Dam T. Son +1
We propose a five-dimensional framework for modeling low-energy properties of QCD. In the simplest three parameter model we compute masses, decay rates and couplings of the lightes…
Constraints on the SU(3) Electroweak Model
Csaba Csaki, Joshua Erlich, Graham D. Kribs +1
We consider a recent proposal by Dimopoulos and Kaplan to embed the electroweak SU(2)_L X U(1)_Y into a larger group SU(3)_W X SU(2) X U(1) at a scale above a TeV. This idea is mot…
The Effective Lagrangian in the Randall-Sundrum Model and Electroweak Physics
Csaba Csaki, Joshua Erlich, John Terning
We consider the two-brane Randall-Sundrum (RS) model with bulk gauge fields. We carefully match the bulk theory to a 4D low-energy effective Lagrangian. In addition to the four-fer…
Supernovae as a probe of particle physics and cosmology
J. Erlich, C. Grojean
It has very recently been demonstrated by Csaki, Kaloper and Terning (CKT) that the faintness of supernovae at high redshift can be accommodated by mixing of a light axion with the…
4D Constructions of Supersymmetric Extra Dimensions and Gaugino Mediation
C. Csaki, J. Erlich, C. Grojean +1
We present 4D gauge theories which at low energies coincide with higher dimensional supersymmetric (SUSY) gauge theories on a transverse lattice. We show that in the simplest case…
