We study of a family of inflation models parametrized by the Hubble radius: The Generalised Gaussian models. They are an interesting extension of the power-law potentials, and are consistent with the current observational constraints on the scalar spectral index and the tensor-to-scalar ratio. The amplitude of primordial gravitational waves in these models are shown to be accessible by future laser interferometers such as DECIGO. We also demonstrate how the observables are affected by the temperature and equation of state during reheating. We find a large subset of this model that can support instantaneous reheating, as well as very low reheating temperatures of order a few MeV.
