Origins of Hidden Sector Dark Matter I: Cosmology
Clifford Cheung, Gilly Elor, Lawrence J. Hall +1
We present a systematic cosmological study of a universe in which the visible sector is coupled, albeit very weakly, to a hidden sector comprised of its own set of particles and in…
An M Theory Solution to the Strong CP Problem and Constraints on the Axiverse
Bobby Samir Acharya, Konstantin Bobkov, Piyush Kumar
We give an explicit realization of the "String Axiverse" discussed in Arvanitaki et. al \cite{Arvanitaki:2009fg} by extending our previous results on moduli stabilization in th…
Stabilizing All Kahler Moduli in Type IIB Orientifolds
Konstantin Bobkov, Volker Braun, Piyush Kumar +1
We describe a simple and robust mechanism that stabilizes all Kahler moduli in Type IIB orientifold compactifications. This is shown to be possible with just one non-perturbative c…
