Scalar cosmological perturbation in an inflationary brane world driven by the bulk inflaton
Da-Ping Du, Bin Wang, Elcio Abdalla +1
We investigate scalar perturbations from inflation in a bulk inflaton braneworld model. Using the generalized longitudinal gauge, we derive and solve the full set of scalar perturb…
WMAP constraint on the P-term inflationary model
Bin Wang, Chi-Yong Lin, Elcio Abdalla
In light of WMAP results, we examine the observational constraint on the P-term inflation. With the tunable parameter , P-term inflation contains richer physics than D-term and…
A plausible upper limit on the number of e-foldings
Bin Wang, Elcio Abdalla
Based solely on the arguments relating Friedmann equation and the Cardy formula we derive a bound for the number of e-folds during inflation for a standard Friedmann-Robertson-Walk…
Modification to the power spectrum in the brane world inflation driven by the bulk inflaton
Bin Wang, Li-Hui Xue, Xinmin Zhang +1
We compute the cosmological perturbations generated in the brane world inflation driven by the bulk inflaton. Different from the model that the inflation is a brane effect, we exhi…
