Asymmetrically warped compactifications and gravitational Lorentz violation
James M. Cline, Luis Valcárcel
In a variant of the Randall-Sundrum braneworld model which has a charged black hole in an anti-de Sitter bulk, the 4D speed of gravity depends upon one's location in the bulk, and…
Dimensional Deconstruction and Neutrino Physics
K. R. S. Balaji
We present a simple observation for neutrino mixings and masses which arises naturally in dimensional deconstruction models. There are two essential ingredients of such models: (i)…
CP Violation in B -> rho pi: New Physics Signals
Veronique Page, David London
A Dalitz-plot analysis of Bd(t) -> rho pi -> pi+ pi- pi0 decays allows one to obtain the CP-violating phase α. In addition, one can extract the various tree (T) and penguin (P) amp…
Spectral Dependence of CMB Polarization and Parity
K. R. S. Balaji, Robert H. Brandenberger, Damien A. Easson
The polarization of the cosmic microwave background radiation (CMBR) can serve as a probe for nonstandard parity violating interactions. Many such interactions are predicted in par…
MSSM Higgses as the source of reheating and all matter
Kari Enqvist, Shinta Kasuya, Anupam Mazumdar
We consider the possibility that the dark energy responsible for inflation is deposited into extra dimensions outside of our observable universe. Reheating and all matter can then…
CP Violation Beyond the Standard Model
David London
I review CP-violating signals of physics beyond the standard model in the B system. I examine the prospects for finding these effects at future colliders, with an emphasis on hadro…
