Cosmology of Brane Models with Radion Stabilization
Csaba Csaki, Michael Graesser, Lisa Randall +1
We analyze the cosmology of the Randall-Sundrum model and that of compact brane models in general in the presence of a radius stabilization mechanism. We find that the expansion of…
The Shape of Gravity
Joseph Lykken, Lisa Randall
In a nontrivial background geometry with extra dimensions, gravitational effects will depend on the shape of the Kaluza-Klein excitations of the graviton. We investigate a consiste…
Wino Cold Dark Matter from Anomaly-Mediated SUSY Breaking
Takeo Moroi, Lisa Randall
The cosmological moduli problem is discussed in the framework of sequestered sector/anomaly-mediated supersymmetry (SUSY) breaking. In this scheme, the gravitino mass (correspondin…
An Alternative to Compactification
Lisa Randall, Raman Sundrum
Conventional wisdom states that Newton's force law implies only four non-compact dimensions. We demonstrate that this is not necessarily true in the presence of a non-factorizable…
A Large Mass Hierarchy from a Small Extra Dimension
Lisa Randall, Raman Sundrum
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 hie…
Day-Night and Energy Dependence of MSW Solar Neutrinos for Maximal Mixing
Alan H. Guth, Lisa Randall, Mario Serna
It has been stated in the literature that the case of maximal mixing angle for ν_e leads to no day-night effect for solar neutrinos and an energy independent flux suppression of 1/…
