Geometrical measures of non-Gaussianity generated from single field Inflationary models

Understand

We have calculated the third order moments of scalar curvature perturbations in configuration space for different inflationary models.

• We developed a robust numerical technique to compute the bispectrum for different models that have some features in the inflationary potential.
• From the bispectrum we evaluated moments analytically in the slow roll regime while we devised a numerical mechanism to calculated these moments for non slow roll single field inflationary models with standard kinetic term that are minimally coupled to gravity.
• With help of these third order moments one can directly predict many non-Gaussian and geometrical measures of CBM distributions in the configuration space.
