On Non-slow Roll Inflationary Regimes
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We summarize our work on constant roll inflationary models. It was understood recently that constant roll inflation, in a regime beyond the slow roll approximation, can give models…
Toward a Gravity Dual of Glueball Inflation
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We summarize and extend our work on nonsupersymmetric solutions of a 5d consistent truncation of type IIB supergravity, that is relevant for gauge/gravity duality. The fields in th…
De Sitter Space in Gauge/Gravity Duality
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We investigate gauge/gravity duality for gauge theories in de Sitter space. More precisely, we study a five-dimensional consistent truncation of type IIB supergravity, which encomp…
On the Stability of D7 - anti-D7 Probes in Near-conformal Backgrounds
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We investigate the perturbative stability of a nonsupersymmetric D7 - anti-D7 brane embedding in a particular class of type IIB backgrounds. These backgrounds are the gravitational…
Glueball Spectrum in a Gauge Theory with Two Dynamical Scales
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We investigate the glueball spectrum of a strongly coupled gauge theory with two dynamical scales. The main tool is the use of the gauge/gravity duality. The model we study has a k…
Scalar Mesons in Holographic Walking Technicolor
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We study the spectrum of scalar mesons in the holographic dual of walking technicolor, obtained by embedding D7 - anti-D7 probe branes in a certain type IIB background. The scalar…
Holographic Walking Technicolor from D-branes
Lilia Anguelova, Peter Suranyi, L. C. Rohana Wijewardhana
We investigate a model of dynamical electroweak symmetry breaking via a dual gravitational description. The gravity dual is obtained by embedding a D7 - anti-D7 pair of branes into…
The NuTeV Anomaly, Lepton Universality, and Non-Universal Neutrino-Gauge Couplings
Will Loinaz, Naotoshi Okamura, Saifuddin Rayyan +2
In previous studies we found that models with flavor-universal suppression of the neutrino-gauge couplings are compatible with NuTeV and Z-pole data. In this paper we expand our an…
The NuTeV Anomaly, Neutrino Mixing, and a Heavy Higgs Boson
Will Loinaz, Naotoshi Okamura, Tatsu Takeuchi +1
Recent results from the NuTeV experiment at Fermilab and the deviation of the Z invisible width, measured at LEP/SLC, from its Standard Model (SM) prediction suggest the suppressio…
A scalar invariant and the local geometry of a class of static spacetimes
Manash Mukherjee, F. P. Esposito, L. C. R. Wijewardhana
The scalar invariant, I, constructed from the "square" of the first covariant derivative of the curvature tensor is used to probe the local geometry of static spacetimes which are…
