We demonstrate the possibility of examining cosmological signatures in theDirac–Born–Infeld (DBI) inflation setup using the BGMPZ solution, a one-parameterfamily of geometries for the warped throat which interpolate between the Maldacena–Nuñezand Klebanov–Strassler solutions. The warp factor is determined numericallyand is subsequently used to calculate cosmological observables, including thescalar and tensor spectral indices, for a sample point in the parameter space. Asone moves away from the Klebanov–Strassler (KS) solution for the throat, thewarp factor is qualitatively different, which leads to a significant change for theobservables, but also generically increases the non-Gaussianity of the models. We arguethat the different models can potentially be differentiated by current and futureexperiments.
