Boundary Inflation in the Moduli Space Approximation
P. R. Ashcroft, C. van de Bruck, A. -C. Davis
The evolution of slow--roll inflation in a five--dimensional brane world model with two boundary branes and bulk scalar field is studied. Assuming that the inflationary scale is be…
Brane World Moduli and the CMB
Ph. Brax, C. van de Bruck, A. -C. Davis +1
The evolution of moduli fields, which naturally appear in higher dimensional models such as brane worlds, and their effects on the anisotropies of the cosmological microwave backgr…
Branes at low energy
Ph. Brax, C. van de Bruck, A. -C. Davis +1
Brane models at low energy are described by an effective action involving gravity and two moduli fields associated with the brane positions. The scalar-tensor nature of the effecti…
CMB Anisotropies in the Presence of Extra Dimensions
C. S. Rhodes, C. van de Bruck, Ph. Brax +1
We discuss the effect of the time evolution of extra dimensions on CMB anisotropies and large-scale structure formation. We study the impact of scalar fields in a low-energy effect…
Gauge Coupling Variation in Brane Models
G. A. Palma, Ph. Brax, A. C. Davis +1
We consider the space-time variation of gauge couplings in brane-world models induced by the coupling to a bulk scalar field. A variation is generated by the running of the gauge c…
Inflation from Tachyon Condensation, Large N Effects
Mahbub Majumdar, Anne-Christine Davis
Using only general properties of the tachyon potential we show that inflation may be generic when many branes and anti-branes become coincident. Inflation may occur because of: (1)…
