Non-standard kinetic term as a natural source of non-Gaussianity
arXiv:0810.3291 · doi:10.1088/1126-6708/2008/10/089
Abstract
We consider reheating after inflation with a non-standard kinetic term. We show that the difference in the kinetic term in different Hubble patches inherited from the long-wavelength moduli inhomogeneities may generate a significant level of non-Gaussianity after inflation.
