SUMMARY:Primordial non-Gaussianity from inflation - Chris Byrnes (Heidelbe

DESCRIPTION:Constraining or detecting any non-Gaussianity in the CMB is a 
 key method for discriminating between the many models of inflation. After 
 briefly introducing the separate universe approach to calculating the curv
 ature perturbation on large scales I present a diagrammatic approach to ca
 lculating the primordial n-point function of the curvature perturbation. A
 pplications of this formalism to calculating the trispectrum (4-point func
 tion) in specific models of inflation are presented.
