Abstract
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 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.
