Primordial three-point correlations in single-field inflation

What changed

Scientific scope

Maldacena calculated leading three-point correlations of primordial scalar and tensor fluctuations in a single-field inflation model. He related a limit in which one wavelength is much longer than the others to the scale dependence of the two-point spectrum. The calculation depends on the paper’s single-field model, perturbative and slow-roll assumptions. It is a theoretical prediction rather than a detection of primordial non-Gaussianity, and it need not apply to every initial state or inflationary model. The examined 2005 revision corrects an earlier error; the journal article appeared in 2003.
