On the Issue of the ζSeries Convergence and Loop Corrections in the Generation of Observable Primordial Non-Gaussianity in Slow-Roll Inflation. Part II: the Trispectrum

Yeinzon Rodriguez, Cesar A. Valenzuela-Toledo

We calculate the trispectrum T_ζof the primordial curvature perturbation ζ, generated during a {\it slow-roll} inflationary epoch by considering a two-field quadratic model of infl…

On the Issue of the ζSeries Convergence and Loop Corrections in the Generation of Observable Primordial Non-Gaussianity in Slow-Roll Inflation. Part I: the Bispectrum

Heiner R. S. Cogollo, Yeinzon Rodriguez, Cesar A. Valenzuela-Toledo

We show in this paper that it is possible to attain very high, {\it including observable}, values for the level of non-gaussianity f_{NL} associated with the bispectrum B_ζof the p…
