Abstract

We calculate the three-point correlation function of the comoving curvature perturbationgenerated during an inflationary epoch driven by false vacuum energy. We get a novelfalse vacuum shape bispectrum, which peaks in the equilateral limit. Using this result,we propose a scenario which we call ``old curvaton''. The shape of the resultingbispectrum lies between the local and the false vacuum shapes. In addition we have alarge running of the spectral index.
