Local Scale-Dependent Non-Gaussian Curvature Perturbations at Cubic Order
We calculate non-Gaussianities in the bispectrum and trispectrum arising from
the cubic term in the local expansion of the scalar curvature perturbation. We
compute to three-loop order and for general momenta. A procedure for evaluating
the leading behavior of the resulting loop-integrals is developed and
discussed. Finally, we survey unique non-linear signals which could arise from
the cubic term in the squeezed limit. In particular, it is shown that loop
corrections can cause to change sign as the momentum scale is
varied. There also exists a momentum limit where can be
realized.Comment: Published in JCA
