Title: "Gravitational Wave Background induced from scalar perturbations in the curvaton model".
Abstract: Curvaton scenario is one of the mechanisms of generating
primordial curvature perturbations and has been focused on
as a model of generating large non-Gaussianity.
Here, we don't care about the primordial non-Gaussianity
and introduce the curvaton model which can generate the
blue-tilted power spectrum of the curvature perturbations.
We discuss the spectrum of the gravitational wave background
induced from first order scalar x first order scalar in such model.
