Running Spectral Index in Noncommutative Inflation and WMAP Three Year Results
arXiv:astro-ph/0603782 · doi:10.1016/j.nuclphysb.2006.08.023
Abstract
A model independent analysis shows that the running of the spectral index of the three year WMAP results can be nicely realized in noncommutative inflation. We also re-examine some concrete noncommutative inflation models. We find that a large tensor-scalar ratio is required, corresponding to a low number of e-folds before the end of inflation in some simple models.
