Covi, Laura; and Lyth, David H. and Melchiorri, Alessandro (2003) New constraints on the running-mass inflation model. Physical Review D – Particles and Fields, 67 (4). 043507 / 9 pages. ISSN 1550-2368Full text not available from this repository.
We evaluate new observational constraints on the two-parameter scale-dependent spectral index predicted by the running-mass inflation model by combining the latest cosmic microwave background anisotropy measurements with the recent 2dF Galaxy Redshift Survey data on the matter power spectrum, with Lyman α forest data and finally with theoretical constraints on the reionization redshift. We find that present data still allow significant scale dependence of n, which occurs in a physically reasonable regime of parameter space.
