… In this Letter, we study the distinctive signatures of the matter bounce in the non-… in the case
of the matter bounce. Then, we turn to the calculation of the non-Gaussianity function fNL and …

… We extend the matter bounce scenario to a more general theory in which the background …
Then, we study the primordial three-point correlation function generated during the matter-…

… non-Gaussianities through the bounce phase. By studying the general … non-Gaussianity
parameter fNL (which is of order unity before the bounce phase) is enhanced during the bounce …

… Whether or not this latter implementation exhibits the large non-Gaussianity problem
discussed in the present paper is still a matter of debate. Second, spatial curvature is identically …

… Our setup utilizes an effective field theory of non-singular bounce, … of the non-Gaussianity
parameter, fNL = (−39.95, −35/8), found within the ekpyrotic contraction and the matter bounce …

… , ie the non-gaussianity generated during the bounce itself, … As we shall see, some sizeable
amount of non-gaussianity is … underlying bounce as well as on the timescale of the bounce. …

… In calculating tensor nonGaussianity we explore peculiar signatures of … nonGaussianity

… -order contribution to fNL comes from A1 and its 2 permutations, and hence is
suppressed in proportion to (−kiτ0) ≪ 1, which makes it difficult to detect the tensor non-Gaussianity …

context of a matter bounce … , we consider the leading non-Gaussianity when modes are at super…

… bounce can collectively account for the anomalous features in the CMB. More precisely, we
argue that a cosmic bounce … In particular, we show that the non-Gaussianity increases the …
