Successfully combining SUGRA hybrid inflation and moduli stabilisation
Stephen C. Davis, M. Postma
Inflation and moduli stabilisation mechanisms work well independently, and many string-motivated supergravity models have been proposed for them. However a complete theory will con…
The Robustness of n_s < 0.95 in Racetrack Inflation
Ph. Brax, Stephen C. Davis, M. Postma
A spectral index n_s < 0.95 appears to be a generic prediction of racetrack inflation models. Reducing a general racetrack model to a single-field inflation model with a simple pot…
Axionic D3-D7 Inflation
C. P. Burgess, J. M. Cline, M. Postma
We study the motion of a D3 brane moving within a Type IIB string vacuum compactified to 4D on K3 x T_2/Z_2 in the presence of D7 and O7 planes. We work within the effective 4D sup…
Moduli Corrections to D-term Inflation
Ph. Brax, C. van de Bruck, A. C. Davis +3
We present a D-term hybrid inflation model, embedded in supergravity with moduli stabilisation. Its novel features allow us to overcome the serious challenges of combining D-term i…
