Abstract

The bispectrum of scalar mode density perturbations is analysed for thestrong regime of warm inflationary models. This analysis generalises previous resultsby allowing damping terms in the inflaton equation of motion that are dependent on temperature. Asignificant amount of non-gaussianity emerges with constant (or local) non-linearityparameter fNL ∼ 20, in addition to the terms with non-constant fNL which arecharacteristic of warm inflation.
