| dc.description.abstract | I will investigate the primordial squeezed limit bispectrum as produced by inflation in single-field models. Previous results have argued that generically, single-field inflation produces a negligible bispectrum. However, more careful evaluation yields a more ambiguous result. I will discuss an alternate method for calculating the squeezed limit bispectrum for a general single-field inflation model. I will also explore slow-roll inflation with a non-standard initial state, where we find an enhanced squeezed-limit. I will discuss the detectability of such models in various cosmological observables such as the Cosmic Microwave Background (CMB), Large Scale Structure, and mu-distortion of the CMB. | en |
