英文摘要: The spectrum of primordial gravitational waves (GWis), especially Us tilt n(T) carries significant information about the primordial universe. (.;Combining recent AKA) and Planck2015+BK14 data, we find that the current limit n(T) = 0.016(-0.989)(+0.614) at 95% also estimate the impacts of Einstein Telescope and LISA on constraining n(T). Moreover, based on the effective field theory of cosmological perturbations, we make an attempt to confront some models of early universe scenarios, which produce blue-tilted CWs spectrum (n(T) > 0), with the corresponding datasets.
